I have about 30 DVDs that I have burned. Some are experiencing problems on playback where they will simply stop playing or go black. What follows are the steps I have taken so far to identify what the problem could be. Any help or suggestions on what would be causing this and how I might remedy the situation would be very appreciated.

My process:

Digital video grabbed from a Canon GL1 (via firewire using Adobe Premiere 6.5 on a Win XP Gateway tower running at 3.2 ghz) and saved as AVI.

Composed in Adobe Premiere using titling, fades, soundtracks. No Affter Effects work.

Exported using Adobe MPEG encoder from Main Concept (v. 1.1-- v. 1.3 is avail but this is the process I used). Settings were default for MPEG stream for DVD NTSC, 720x480, FPS 29.97, 4:3 display, Audio set to 48khz, no multiplexing.

Burned using Sonic Solutions DVDit! LE (bundled, v. 2.5) with no menu. Included WinDVD for playback.

Media was primarily Imation DVD-R discs with a couple of Memorex discs thrown in at the end.

Research:

I have currently tested 4 DVDs on various platforms (mac, win 2K, XP, set top boxes). All have similar results regardless of platform. I have run DVD Info Pro and discovered LBA (Logical Block Address) errors on 2 of the 4. 1 does not seem to have any LBA errors but still freezes. 1 is just fine (runs and has no LBAs). The point at which these 3 DVDs freeze seems to be around the 30min mark (give or take a min and some sec). I have also dwnlded Nero although I have only run it on one of the disks with similar results as DVDIP.

Adobe says that they haven't heard of any such problems using their workflow (provided the defaults were used).

I have also gone back and burned another DVD using the above named process but with different media (Verbatim DVD-R).

Conclusion:

Either I (somehow) screwed up the process (varied from the defaults . . .) or the media is bad. My guess is that it is me or my process. Any thoughts?

Solution:

I can go back, reburn all the bad DVDs (I have all the vid backed up to tape so it would be something of a laborous process but doable) and see if that doesn't fix them (perhaps using a different process, hardware, software?).

Would there be a way to rescue what I currently have from the offending DVDs and reburn them to a new DVD? Wishful thinking I know but hey, it is Christmas

Thank you in advance for any and all help or suggestions.
