Yes. With was previous soundcard it was pretty obvious. In 1 hour the audio was
delayed by .1 of a sec. In 2 hours by .2 of a sec for NTSC video. And all the
DVDRs I watched that I made were perfectly in synch.

I use a TV Tuner card
(http://www.lifeview.com/html/product...deo3000-w1.htm) to transfer
an analog video from either VHS or LaserDisc to my computer. I connect VCR's
S-Video cable or LaserDisc Player composite cable to this Tuner card. I capture
in AVI file. If I x-fer from VHS, I use an RCA audio cable to run from my VCR
to my soundcard. And of course I sample audio at 48kHz to be DVD compatible.
If I x-fer from LaserDisc player, I use optical digital cable from LD player to
optical digital in of my soundcard. There I set an audio at 44.1kHz that I
later manually resample at 48kHz as postprocessing procedure. Pretty straight
forward, but time consuming if you are shooting for a good quality.

And yeah, I noticed that I screwed up a little. My soundcard was locked at
44.1kHz while my application was set to 48kHz. Besides resampling on the fly,
that may have caused audio alignment to be ahead.
