DVDWS2 audio & video synchronization
on Jul 22, 2004 at 11:54:09 pm

PROBLEMS:

1) video not synched (20-30 sec ahead) with audio during playback
2) audio on & off repeatedly and unpredictable during video playback
3) video choppy as if fast-forwarding at 1.5x during playback
4) switching between menus you can see bottom of previous menu as it switches to next menu; seems like a type of lag in response time or something

BACKGROUND:

1) decrypted VOB video files from a DVD using DVD Decrypter v3.2.3.0
2) imported VOB video files into DVD Shrink v3.1 in attempt to compress to one disk
3) compression quality was horrible so re-authored to 2 disks
4) discovered re-authoring in DVD Shrink causes loss of all menu functionality
5) imported re-authored VOB video files into Ulead DVD Workshop 2 to create new menus after ensuring video was in perfect order (tested by burning to DVD-RW’s)
6) appeared DVD Workshop 2 converted VOB video files into MPEG video files
7) changed burn template settings to match these MPEG video files as closely as possible:

a. 29.97 frames/sec
b. 720 x 480 resolution
c. compression 80% (I left it at default but didn’t know if I should change to 100 since it was already compressed prior with DVD Shrink and no further compression is needed)
d. variable data rate at 9800 kbps
e. I tried each of the formats: MPEG, LPCM & Dolby Digital
f. 48000 Hz audio frequency
g. 192 kbps audio bit rate

8) encoded completed project to an ISO image file in DVD Workshop 2
9) burned ISO image file with Nero v6.0 to DVD-R to discover the above problems

CORRECTION ATTEMPTS:

1) encoded ISO image with DVD Workshop 2 direct to DVD-RW avoiding Nero altogether; no luck
2) opened each MPEG video file Ulead DVD Workshop 2 created in the VOB video file import process to ensure video was in perfect order; video files were perfect
3) tried lower burn template settings; no luck

Anyone have any ideas? I don’t see what I’m doing wrong. I don’t think it’s a burner or a media problem since I’ve burned hundreds of VOB files on DVD immediately after using DVD Shrink without any problems. At that time I wasn’t interested in menus but now I am! Please help me out I’d greatly appreciate your input. I am completely stuck; dead in my own tracks until this problem can be fixed. I thought I’ve tried everything. Thank-you so much for your assistance.

Try using a program called "IFOedit" to fix any menu problems after using DVD shrink
