Further to my prior posts, I have been desperately trying to learn how
to burn RTV .mpg files to DVD without transcoding. I have now purchased
Nero 6 Ultra, which includes NeroVision and other DVD functions. I
opened an RTV .mpg file in NeroVision and wrote it out to the hard
drive, where it was saved as .vob and other DVD-appropriate files. For
the first time, after burning the files to one of my dwindling supply of
DVDs, the audio and video quality are as good as the original file
(probably meaning that the file was not transcoded). However, the audio
is lagging behind the video. What gives?

Your trying to use raw RTV files as a source.
RTV files are not truly mpeg compliant.

I opened the file in VideoReDo, ran Quick Stream Fix, and burned it to
DVD using Nero 6 Ultra. Everything is in sync.

There are differing opinions here as to whether the files created by RTV
in the medium mode are "standard" mpg files. Apparently they are not, as
you say.

THere are several MPEG standards.

Video CDs (VCD) contain MPEGs to MPEG-1 standard. DVDs contain MPEGs which
are MPEG-2. I have read that the DVD spec includes MPEG-1, but any time
I have wanted to include an old MPEG-1 onto a DVD, my authoring software
wants to re-code to MPEG-2. So I usually don't bother, and just run it
out to VCD.

I should also add that Replays use MPEG-2, NOT MPEG-1.

Standard MPEGS from video cd require a treatment with RTV Tools
rtvconvert.exe to play on an RTV.
If RTV was using standardized mpeg, why would already standard files require
modification?
That's the circle of logic I get stuck in.

Xvid is a "loose" adherence to mpeg, but it is screwy..

This is one description I found about this issue:
"Technically, ReplayTV's MPEG encoding, though DVD-compliant at Medium
Quality, often introduces errors that can wreak havoc on most DVD authoring
programs (including DMF2.) Typically, the file contains PTS (Presentation
Time Stamps) errors, and sometimes GOP (Group Of Pictures) errors. So, the
..MPG file needs to be "cleaned up" somehow so your authoring program can
import it. These errors are notorious for throwing your audio and video out
of sync. "

So it may be compliant, but sloppy as hell..?
