If you could describe their differences in a simple way, I'd be very grateful.

Unless I'm terribly misinformed. :-) BlueRay and HDDVD are the next generation of High Definition recordable media, with expected capacities of up tp 50gb per disc (4 layers). This is achieved by using a new smaller Blue laser, hence the name :). BluRay is being developed primarily by Sony and HDDVD is being led by Toshiba. The problem is that different movie companies have backed different formats which has led to somewhat of a stalemate, and it looks like you will need to have a player for both types of disc in the future. For those of you who are interested to find out more, I learnt all about this from http://www.avforums.com/forums/showthread.php?t=139511&page=1&pp=15, a great forum for all things AV related (www.avsforums.com in the US I think). The concensus on this forum is that DVD-R is probably the best recordable media for compatibility purposes, but the manufacturer is important too.

Just so you know, I'm a bit hesitant to go and buy another set of discs since I know the ones I have do work, just not in Debian. I'll probably use these up by creating an image then burning it in Windows until I run out of discs before I get a new set to try.

I was just going to ask you if you had problems with DVD+RW media, but, then, I saw that you said it was fine. My DVD writer is an HL-DT-ST DVDRAM GSA-4160B (according to dmesg) and it works fine with DVD-R media, but has some troubles with DVD-RW media (I would tell you to avoid that, based on my experience). Perhaps I had bad luck with the media that I used (two brands, can't remember their names), but sometimes the DVD writer wouldn't even recognize that there was a disc inserted. Anyway, just out of curiosity: are you able to read all the DVD discs that you burn on regular computer or standalone drives? I have only had success when using DVD-R media, not with the other variants (DVD+RW or DVD-RW; I don't have DVD+R media). I'm carbon copying this to debian-powerpc because I am quite curious to know if *ONLY* the superdrive equipped notebooks are able to read all meddia or if all the current-selling models (including the cheaper combo drive models) can read such media. My iBook's combo drive (it's an iBook 600MHz, Late 2001 model) has problems even with some DVD-R media that was spec'ed to be burnt in 8x, which is a bit frustrating. :-( Thanks in advance for any comments, Rogério Brito. -- Rogério Brito : [EMAIL PROTECTED] : http://www.ime.usp.br/~rbrito Homepage of the algorithms package : http://algorithms.berlios.de Homepage on freshmeat: http://freshmeat.net/projects/algorithms/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

DVD+R writing problems
Recently I upgraded my disc burner to a LiteOn SOHW-1693S Dual Format Double Layer DVD burner. I've been trying it out but I've run into problems trying to burn DVD+R discs. Of the 50 or so tries so far (many with different discs, all from the same manufacturer), only 4 have been successful. When I try to burn a DVD+R the drive spins up, slows down, spins up again, slows down, and cycles like this, without burning any data, for about a minute before I get the error: growisofs: 5.21 growisofs --- Executing 'builtin_dd if=/home/brendon/debarchives.iso of=/dev/hdc obs=32k seek=0' /dev/hdc: "Current Write Speed" is 8.2x1385KBps. 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? 0/3449405440 ( 0.0%) @0x, remaining ??:?? :-( unable to [EMAIL PROTECTED]: Input/output error :-( write failed: Input/output error Physically looking at the disc after this it appears that a small track on the inside of the disc has been burned, but this seems to make no difference to the empty/full state of the disc, or its ability to be burned to subsequently. For the first few tries, at least. Each time I try to write on a disc this burned strip seems to get slightly wider. At first I suspected that perhaps I had managed to buy a set of discs that my burner just didn't like. To test this hypothesis I booted into my remnant Win98 partition, installed the burning software, and tried again to see what it would do. The disc spun up, slowed down, spun up again, perhaps it cycled like this a few times, and then began to burn the data, a good step beyond what I was able to achieve on the same disc in Debian. (I'm running Sid, BTW). My next thought was that perhaps the windows burning app gave the drive a bit longer to find the start of the disc (or whatever its trying to do when it spins up/down like that). After my attempts to find a timeout option for growisofs failed, I did a stopwatch test to see how much time it did actually take to start writing in the windows app and fail in growisofs. The result: windows starts burning in about 40 seconds, well before growisofs returns with an error (about a minute). So now I'm stumped. Do note that the problem only seems to be with DVD+R discs. CD-R, CD-RW, and DVD+RW writing is fine (although consistently slower than advertised, this is probably a different issue altogether). I have no DVD-R/RW media to test, so I have no idea if they fair any better. I'd like some ideas about what I should try and how I can go about troubleshooting this.
