Write problems with unbranded DVD[+-]RW drive...
Greetings all, At the weekend I got an unbranded DVD writer - I was in a local electronics shop, it was on offer very cheap. I have *a lot* of data to archive, and it seems like a bargain... Claims to support + and - RW writing. (The retail box is marked PIKA ONE, but the drive itself is unbranded.) Installed the latest cdrtools from source. It's what I know, so it seemed sensible to stick with it, it's always worked well before... Installed in place of my CD burner, burned some test CD's with cdrecord, all worked fine. Installed Ogle and checked I could watch DVD's smoothly - worked fine. Installed cdrecord-ProDVD test binary. A test run -dummy went smoothly, but the actual burn failed (see sample failure below). This is with Verbatim 4x DVD-R media, in case that matters. Fiddled about with hdparm in case my DMA settings were a problem, no better. Tests with dvdrecord fail in exactly the same fashion (and again the dummy run is good.) (coaster count now at 4 and rising...) However, tests with dvd+rw-tools (my 3rd scheme...!) have all worked perfectly, both with DVD-R and DVD+RW media, so I guess that basic drive is OK. At least, I can read the disks it's written back on my Mac, so I guess that's OK! Is it likely something in my setup that's upsetting the cdrecord derived tools? How do I pin this down and fix it? Base system is linux, with a 2.4.16 kernel, latest cdrtools tarball... what else do we need to know? TIA for input. cdrecord-ProDVD output follows...

RE: Write problems with unbranded DVD[+-]RW drive...
Rob, Fiddled about with hdparm in case my DMA settings were a problem, no better. I hope that means that you saw that DMA was on. You want DMA, and if the DMA doesn't come on by itself, it sometimes means it will have problems (my DVD-104 needed an update to 1.40 firmware before the DMA defaulted on at boot time). Well, according to hdparm, DMA is not defaulting to on on this drive. But turing it on with hdparm seems to work (although my testing of this lacks rigour - i.e. run Ogle, watch how jerky it is, check CPU load. Turn DMA on, run Ogle - smoooth motion, lower CPU load...) However, in my attempts to get the writing to work, I tested with DMA on and off, with broadly similar results. Indeed, (subjectively) writing seems *less* flaky with the DMA *off*. Which seems so wrong to me. Also, most of the disks I have managed to burn with dvd+rw-tools have been with the DMA *off*. Well, I'm pretty sure it's off - not at that machine just now... While I have one + drive, I haven't tried + media in it, I find no advantage in price or speed, and a backup is a backup, the DVD-R read okay on more DVD-ROM drives I have, so that was the end of my interest. Well, I had the DVD+RW media anyway, and no -RW disks, so it made sense to test it. Indeed, the Mac managed to read the +RW disks fine, and it has a DVD-drive in it (a Pioneer) so I guess that's all the compatability testing I need for this job!

Re: Why does cdrecord turn burnfree off by default?
From: Samuel Tardieu [EMAIL PROTECTED] The manpage of cdrecord says: The default is to turn BURN-Free off, regardless of the defaults of the drive. What is the rationale for doing that? Shouldn't burn-free be turned on by default, or at least be let untouched by cdrecord to preserve the writer's default behaviour? Its the SCSI standard. and CDs with Burnfree are of worse quality. Leaving it untouched would cause cdrecord to behave unpredictable.

Re: Re: DVD recording adventures continued
I just asked Plextor for the neexed info. Lets see what happens... Pleased to hear that :) I just sent a mail (see below) to [EMAIL PROTECTED] Maybe some more people reading this list can send similar requests? Not all of you have a Plextor, but you can duplicate and send to other manufacturers too. Perhaps also to info@ addresses as potential customers (that did not already buy, but would if Linux is supported..) OK, that probably wont change much, but at least we have to try :) FL --- support request Hello Plextor, I purchased your DVD recorder model 708. I want to run it with Linux. You link to some resources on your website at page http://www.plextor.be/English/technical/linux.html CDrecord does not at all work with the 708. I know this is not primarily your responsibility, but I want to express my request that you do everything to support the author. There is another project named dvd+rw-tools, that currently works in many cases with the drive: http://fy.chalmers.se/~appro/linux/DVD+RW/ Perhaps you can add it to the Linux-page? Another chapter is firmware updates. The author of cdrecord also maintains a Linux flash utility, but it also does not know the 708 yet. Again, please supply the author with all necessary information or hardware as soon as possible. The firmware itself is packed into an .exe - why dont you use a standard format like zip? At least alternatively. I am sure there are more users interested in recording on Linux - please reconsider to increase your commitment regarding Linux. If Plextor becomes the brand of choice for Linux users, this is a target group that may be more valuable than its pure number suggests. Maybe Plextor already is better for Linux than many other brands - but it sure is far from real good.. One thing is sure: the Linux community is growing. Multimedia with Linux is gaining ground (mplayer, VDR). Lots of people build their own HD+DVD-videorecorders on this basis. Thanks for reading.

Re: Write problems with unbranded DVD[+-]RW drive...
Yup. Asked for 1 - reported 4. But I think on a fail it probably isn't true? Still, the drive and the media are both spec'd to support 4x writing, so that in itself shouldn't be an issue I guess, anyway. My experience with DMA is that having it off can seriously stuff the kernel's time keeping, with the result that it needs 20min to advance 10min, causing throughput rates to be displayed off by a factor of 2. This even happens on recent 2GH P4 hardware. If you want to find out actual writing speed reliably, you need to find out how many bytes were transferred and take the time using your wrist watch. In theory, writing over USB 1.1 (1MB/s, appr 0.8x) is fine if burnproof/whatever is turned on in the drive, it's just slower. DVD+RW doesn't even need anything special, it'll just be slower. Likewise if DMA is off and the system can't supply data at the required speed (indication of this is 100% CPU load). Kernel-time being stuffed doesn't cause faulty disks by itself. Recently I had the case of a box just crawling, couldn't find out why, CPU load displayed as close to 0. Kernel-time was fine, DMA on, but burning DVD+RW still only proceeded at 0.6x. No doubt it would have worked, but a reboot was faster.

Re: DVD+/-R writers
If you continue to repeat the marketing lies from the DVD+ alliance, nobody would believe you. Perhaps the DVD+- are telling lies about each other, wouldn't be surprising. If you believe that DVD+ is able to do things DVD- can't so please name these features. Going by my own observation and not what someone tells me, it seems random access write to DVD+RW is rather easier than to DVD-RW. I don't have to blank the disk, and it still works at 0.1x speed. Andy's DVD+RW kernel patch isn't meant for DVD-RW - could this be because DVD-RW doesn't allow something? +/- compatibility issues are just a question of time, one would assume dvdrom anything which can only read - are no longer being made. cdroms were in a similar position once.

Re: DVD+/-R writers
From: Volker Kuhlmann [EMAIL PROTECTED] If you like to buy a single format writer, buy DVD-, it is standard has less readibility problems As you keep on propagating this nonsense (one might also call it FUD), for the record: DVD+ isn't any less standard than DVD-. Anyone can call themselves the standard. Despite the FUD the DVD- people are putting out about DVD+, DVD+ isn't going to go away because it has a few things to offer DVD- couldn't possibly dream of (hence the need to resort to dirty tricks). As I can make out DVD+ is gaining momentum, and personally I wouldn't dream of buying a single-format burner - I imagine most people might think the same and the days of single-format burners are numbered. Any decent player has no problems with either DVD- or DVD+ as long as the media quality isn't rock-bottom. If you continue to repeat the marketing lies from the DVD+ alliance, nobody would believe you. If you believe that DVD+ is able to do things DVD- can't so please name these features. It is rather the other way round. DVD+R and DVD+RW are two disjunct formats and both offer only one write method. DVD-R and DVD-RW build a group and support several write methods - including what DVD+ offers.

How did you do it? If you used a Linux tool, I would be very interested in the details.. I just asked Plextor for the neexed info. Lets see what happens...

Re: Write problems with unbranded DVD[+-]RW drive...
From: MacArthur, Ian (UK) [EMAIL PROTECTED] At the weekend I got an unbranded DVD writer - I was in a local electronics shop, it was on offer very cheap. I have *a lot* of data to archive, and it seems like a bargain... Claims to support + and - RW writing. (The retail box is marked PIKA ONE, but the drive itself is unbranded.) Installed the latest cdrtools from source. It's what I know, so it seemed sensible to stick with it, it's always worked well before... Installed in place of my CD burner, burned some test CD's with cdrecord, all worked fine. Installed Ogle and checked I could watch DVD's smoothly - worked fine. Installed cdrecord-ProDVD test binary. A test run -dummy went smoothly, but the actual burn failed (see sample failure below). This is with Verbatim 4x DVD-R media, in case that matters. Fiddled about with hdparm in case my DMA settings were a problem, no better. Tests with dvdrecord fail in exactly the same fashion (and again the dummy run is good.) (coaster count now at 4 and rising...) However, tests with dvd+rw-tools (my 3rd scheme...!) have all worked perfectly, both with DVD-R and DVD+RW media, so I guess that basic drive is OK. At least, I can read the disks it's written back on my Mac, so I guess that's OK! Is it likely something in my setup that's upsetting the cdrecord derived tools? How do I pin this down and fix it? Base system is linux, with a 2.4.16 kernel, latest cdrtools tarball... what else do we need to know? TIA for input.

Re: Re: DVD recording adventures continued
I just asked Plextor for the neexed info. Lets see what happens... Pleased to hear that :) I just sent a mail (see below) to [EMAIL PROTECTED] Maybe some more people reading this list can send similar requests? Not all of you have a Plextor, but you can duplicate and send to other manufacturers too. Perhaps also to info@ addresses as potential customers (that did not already buy, but would if Linux is supported..) OK, that probably wont change much, but at least we have to try :) FL --- support request Hello Plextor, I purchased your DVD recorder model 708. I want to run it with Linux. You link to some resources on your website at page http://www.plextor.be/English/technical/linux.html CDrecord does not at all work with the 708. I know this is not primarily your responsibility, but I want to express my request that you do everything to support the author. There is another project named dvd+rw-tools, that currently works in many cases with the drive: http://fy.chalmers.se/~appro/linux/DVD+RW/ Perhaps you can add it to the Linux-page? Another chapter is firmware updates. The author of cdrecord also maintains a Linux flash utility, but it also does not know the 708 yet. Again, please supply the author with all necessary information or hardware as soon as possible. The firmware itself is packed into an .exe - why dont you use a standard format like zip? At least alternatively. I am sure there are more users interested in recording on Linux - please reconsider to increase your commitment regarding Linux. If Plextor becomes the brand of choice for Linux users, this is a target group that may be more valuable than its pure number suggests. Maybe Plextor already is better for Linux than many other brands - but it sure is far from real good.. One thing is sure: the Linux community is growing. Multimedia with Linux is gaining ground (mplayer, VDR). Lots of people build their own HD+DVD-videorecorders on this basis. Thanks for reading. Your hopeful customer..
