what is MPA T01 DELAY -103ms ??

[alucard2050]

i am capturing from a ATI Wonder card. i am capturing useing the preset for best quality. when i use DVD-AVI i get the video file normally but the audio file is labeled with MPA T01 DELAY -103ms. then i encode the video useing TMPGE. could this type of audio be the reason why when i create a vcd and play it on my home theater system the sound only comes out of 1 channel?

This shoudl actually be the delay of audio to video once it's been ripped from your capture source.

Normally, what you have to do, is apply a delay setting (either as you re-encode in TMPGEnc, or as you multiplex) so that your audio/video will be in synch again.

So in your case, of -103ms, you would go to TMPGEnc's "Source Range" feature, and select your start/stop frames, and add 103ms to the audio offset.

Now, I should say this only really works this well if you take the audio stream DVD2AVI puts out (assuming a ripped .ac3 or .mpa stream), then RE-ENCODE IT TO WAV FORMAT! (If you use WinAmp's "DiskWriter" output plugin, it works on .mp2's in seconds). Anytime you work with a compressed format, you'll likely get another delay applied to a re-encode.

Sorry if that sounded confusing. Let me just list the steps you should do and you'll be fine.

1) Source movie --> DVD2AVI --> DVD2AVI generates new WAV --> TMPGEnc (or whatever) re-encodes.

OR

2) Source Movie --> DVD2AVI -->DVD2AVI generates ripped .mp2 or .ac3 delayed stream --> Convert to WAV --> Re-encode (with audio offset applied)

Good luck!

Failed to mention, if you're getting no audio on something, this won't help that probelm. That might be more likely which track you rip in DVD2AVI. Usually the main audio is on track 1, but sometimes you have to hunt for it...
