DVD-A2 wants to recompress all

Okay, I can see if it doesn't like TMPGenc files (though they are fully compliant) but when I render with Vegas 5.0 Mainconcept, and still it doesn't like the audio or video. Telling it not to recompress is useless and the sizes are so off it scares me to death ...SONY PLEASE FIX

I do not want to wait 35 minutes for a file to recompress when a normal prepare will take 7 minutes (10 minute video clip)

UGGGGGGGGG..Buggy Buggy

If all you've got is a 10 minute video, something else is wrong. I don't know of a DVDA2 bug that would cause it to recompress a 10 minute video if the video is compliant.

What were your encoding settings in Vegas? Original aspect ratio? DVDA project aspect ration? Type of audio?

It was all default settings for DVD NTSC
MPEG 2 / VBR 6000 / audio I upped to 384

Funny thing was I exited the program, came back in and now it did not want to recompress. It does not always do it. I gave it a 1 hour wedding video that was rendered with TMPG ...VBR 7000 and it liked it just fine...hmmm

I just wish there was a simpler way to say DO NOT RECOMPRESS. Why does it ALWAYS recompress audio ? Every time, created by vegas or not

Sorry , one other question. Can I tell it 5.1 even if the source is not ? What would the result be ? It would be nice to have a 5.1 encoder that would take say a stereo channel, analyze, and break into 5.1.....Okay

Because, in DVDA, MPEG audio is not an option. Your DVDA can have PCM audio or AC3 audio, but not MPEG audio. Since you're dropping just an MPEG2 file (with, I assume, the audio included within it), DVDA has to seperate the audio, encode it into PCM or AC3 (depending on the settings you've chosen) and then add it to the final VOB files.

Your choice is to let DVDA re-encode the audio or to render out the audio (as an AC3 or WAV file) yourself and then use that for the audio stream in DVDA. Vegas will do the same thing that DVDA wants to do, but will be a little faster.

Hi,

I understand what your saying but doesn't that seem to defeat the bundling of Vegas and DVDA ? I mean , EVRYTHING that creates an MPEG2 creates MPEG audio so DVDA (and Vegas ) should do one of two things

1) DVDA accept MPEG2 audio
or
2) Vegas by default, ouput seperate elementary streams with an easier interface in DVDA to accept.....

Okay, but now I have my answer so I need to post another questions....About 5.1 surround
