Did you set the DirectShow priorities to two or higher?

Are you by chance talking about the Two Towers? If so, there is a glitch in one of the files. I think you have to edit out the bad frames and reburn.

...am having same problem with Two Towers CD1...at 7:50 minutes into it the video goes bad....I've tried cutting and joining the file to edit out the bad part however it screws up the audio....am going to keep working with it...hopefully virtual dub can fix this....Wish me luck

The TT XviD cd1 file has bad frames. To fix them, you will need VirtualDub with MP3 freeze and VirtualDubMod. These are both available as freeware, just Google search for them. Open the CD1 file in VDubMp3 and under Video, Scan for Freezes. This will take a minute and output a "badframes.log" file to your C:\ drive. There should be only one set of bad frames(ie. 11229 to 11255).

Open the file in VDubMod. Under Edit, Go To the last frame that is bad. Hit the next keyframe (looks like a key pointing right) button. Click the arrow on the far right (pointing right) to make this the end of your selection. Go To the first bad frame, go to the previous key frame, and make this the beginning of your selection. Cross your fingers and press Del.

Select frames 0 to 11229 in the way described above. Save As with "Direct Stream Copy" for video compression. This will save the first part.

The second part will have a/v sync problems. Under Streams, select View streams (or something) Right click the audio stream and select interleaving. Enter a skew correction value of -250ms (this should work)
Select frames 11229 to the end and Save As with Direct Stream Copy.

Close and reopen VDubMod. Now we join the two AVIs together. Open the first, go to File -> Append Segment, and add the second. Save with Direct Stream Copy to another AVI.

To get TMPGEnc to handle both files, we need to reencode them to DivX 5 with PCM audio. For each, open in VDubMod. Under Video, select Full Processing Mode. Under Video, select Compression and choose DivX 5 (you will need the DivX player) Under Streams, select View Streams. Right click the Audio and select Full Processing Mode. Right click again and select Compression. Choose No Compression <PCM> Save each to an AVI.

Finally, encode each AVI with TMPGEnc. You don't even need to bother with WAV files for audio. Post any questions here, I will be happy to help.

I've downloaded the two cds for the Two Towers, and primarily with the first one, there is problems with the a/v sync. The audio is slightly delayed, just enough to be annoying. It seems pretty constant throughout the movie. Perhaps others have had this same prob? The second cd appears to be slightly off, also, but it is better. I've tried extracting the audio to a WAV format, but then the sound doesn't seem to be able to be directly synced with the video, it seems almost as if the sound needs to contain all the same info, but be shrunk, or stretched? Tried doing this with Adobe Premiere 6.5, but doesn't seem to actually compress the length, but rather that it's deleting some off the end? Much Thanks for any help!

Sounds like you're having a problem with your XviD codec. If you needed to strech the audio, then the sync would gradually get better throughout the movie and then get worse in the opposite way (i.e. video before audio gives way to audio before video). Try using the Nimo Codec Pack, but first uninstall your old XviD codec. Also, I have had profound problems with extracting the audio to WAV, so don't try. Seems like VDub shaves off the beginning part ("...for academy consideration only..."), creating an even worse sync problem. If all else fails, try a skew correction in VDubMod.

P.s. make sure you DO use VDubMod. VirtualDub is known to cause sync problems with this movie. Also, tell VDubMod NOT to rewrite the VBR encoding--this will also create sync problems. Hope this helps.
