A/V synch issues...

[ChaunceyK]

I'm using ADS DVD Xpress to capture from old vhs tapes, about 2 hours 45 minutes worth of a/v straight. It looks & sounds fine when I test the .mpg afterwards. Then I use TMPGenc DVD Author to create the menus & chapter points. Still looks & sounds fine while doing so. Then when I output it to a dvd folder & test it from there (with WinDVD), the audio starts off in synch, but gradually loses itself with the audio being a good 2 or 3 seconds behind by the end. To be sure, I even burned it to a dvd-rw to make sure it wasn't WinDVD, and the loss is accurate.

Someone had recommended about 3 weeks ago that I use PVAStrumento, which worked fine for another capture. But now I'm getting a/v synch problems again...partly because I don't remember exactly what I did the first time. I've experimented with it a few times now, and I'm still just not getting accurate results.

Pushing the buttons on the program is simple enough, but I'm confused as to what I need to do since I'm not familiar with the terms "demux, pva, and ps"...should Info, Scan, and Demux completely repair my .mpeg, or do I need to do something with pva and/or ps as well?

Well, 10 hours later & still not a reply...I guess my problem must be more difficult than I thought. Either that, or people find it more satisfying to argue over whether the word "help" should be banned from being in a topic on a board called "videohelp" (redundancy intended).

Anyway, since the 10 hours ago, I've tried more variations on using PVAStrumento, to no avail. I still get the same results. I've also tried Simple De-multiplexing with TMPGEnc & then using the resulting .mp2 & .m2v files in TMPGenc DVD Author, also to the same results.

I'm trying to help myself out here by trying various potential solutions, but I'd appreciate it if someone could give me some guidance since I keep getting the same results.

rookie here, but ill toss in my 2 cents. ditch tmpgenc and try mpegvcr to cut the mpegs, and nero to build the menus etc. i had ur exact problem, and this worked for me. yea the softwares expensive, but at least u can try them out for free and see if they work for u

I've had good results cutting commercials out of MPEG2 captures using MPEG-VCR. No sync issues like I usually got with other programs, including the "tools" in TMPGEnc.

Sometimes you can't go by software players, and in the end, you
have to burn to a DVD disk for the final test.

Otherwise, I would theorize that somewhere's in your setup, you
are dropping frames, and the ADS is not telling you this.
.
Just because it's a hardware mpeg device, does not mean that it
won't drop frames, or audio for that matter. It could be your
tape. How knows. But the only way to know this for sure is to
put in a healthy tapes (commercial tape) and capture it, and then
see if the same problems arrise. If they do not, then you have
your answer. It's your old tapes causing you the problems. Could
be dropouts orsomething. Who knows

I've used womble mpeq video wizard (similar to mpeg vcr) to edit, and then created menus and burned with TMPGenc DVD Author 1.6 without any AV sync problems. Although I've never done 2 hours and 45 minutes worth. As a previous poster says, these can be expensive but you can fiddle with them for thirty days. I usually use the burning tool that comes with DVD Author.

I don't know enough to offer much other advice. Maybe you could go to the time code where AV sync starts to get bad and put in a cut, and then use Goldwave to "warp" the sound track back to the correct time from that point on. Out of my league on demuxing and such.
