DVD burner optimization (or how to avoid crappy burns)
I've been burning for about a year with my ultra cheapy MicroAdvantage DVD burner. It seems to work, but I've noticed on a majority of the disks I've burned, somewhere midway in the disc it'll kinda crap out and show compression artifacts, get jerky for a few moments (usually under 30 seconds), and just plain be a nuisance. This will usually affect only around a 5% time duration of the video if that. Ie., I can usually still watch the DVD. It's just annoying though. I've been suggested to burn at a slower rate, and I've switched to running growisofs with -speed=1, and that has helped (I think anyway), but I still get the above problem _sometimes_ (with identical content). Again, it's an intermittant problem, so I can't quite put my finger on what the problem is stemming from. This could be a fluke, but it seems I have better luck when I burn a disc from the terminal fresh after booting into Linux and before I log into any window manager. I need to test this some more. Anyway, my question is: are there any other ways I can adjust my system/burn process to prevent artifacts, etc. from creep onto the DVD? Would 'hdparm -d1 /dev/dvd' maybe help? Or maybe using 'nice'? FYI, here's the command I run to burn a disc: growisofs -speed=1 -Z /dev/dvd -dvd-video DVD/ Thanks for reading! Eric P. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Or maybe using 'nice'? Odds are it isn't your burner, it's your DVD player. If the DVD plays back on your PC without problems then the data are fine -- what's happening is your DVD player is having problems with the DVD-R (+R, -R/W, blah...) media. I presume it is due to the different reflectivity and/or lower tolerances of the consumer writeable DVD media relative to that of commercial DVDs. Older DVD players seem to have more problems than newer models. Some people have found that switching to a different brand of DVD media solves the problem with their player. YMMV. (I gave up and just use my DVD burner for data now. I consider it an incentive to get off my ass and build a mythTV box :-) -- Brad -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
