i take it you ripped a dvd and ended up with a ac3 file with a long name and part of that name is 80ms delay ..

well first - rename the file to dos conventions (8.3 naming )

then rename your video stream the same except for the file exten.


import those into spruceup ...

ac3 files from disney have timecode inthe ac3 file and will lock to the video (in spruce maestro anway, i suspect in spruce up also)

if your ac3 file is damaged - you should re-rip it ..

BJ_M i have renamed the file so that they have both (the video and sound) have same name, but it imports about 99% and sais inconsistant bitrates, im not sure how to get around this, any ither ideas?

[BJ_M]

it is because the menu and credits have different bit rates .. since it says it at the end it may be just the credits OR may be just the very end ..

you will have to rip by chapter or edit the ac3 stream or re-encode the ac3 stream completly (not suggested) ..

you can edit the ac3 stream with vitec dvd tools - but it may be easier for you to rip credits out ..

if it is just the VERY end -- use a file cut tool and cut the end of the ac3 file - last 1k is good start. you can accually do this with winrar if you dont have a file editor ... Split files - store only (no compression) .. rename part one back to origanal - throw away part 2 ..

the audio can be shorter than the video stream -- no big deal

[BJ_M]

if you had Maestro you can make a ac3 sync track (writes a new ac3 file) -- which may get around the problem also ...
