Can I stop DVDA 1 from rerendering?

I didn't see an answer to this in earlier posts, so...

I have a presumably (not positive because I didn't render it myself) complaint MPEG-2 mpg (audio & video muxed) the size is small enough to fit on a DVD with enough room for menus, etc. When I try to author this in DVDA v1, it wants to rerender the video. (I mean 6 hours worth of rerendering, so yes, it is rerendering the video). Is there any way to avoid this?

I'm thinking I can workaround the problem by demuxing the file using TMPGEC, and the remuxing the elementary video stream with an empty audio stream to try to get a DVDA 1 compliant video file. Seems pretty kludgy, though. Anyone know if this will work?

I understand that DVDA 2 will accept elementary streams, but so far I have not felt the need to upgrade, as I usually render stuff out in Vegas 4 for DVDA. Would I have the rerendering problem with my original mpg file in DVDA 2?

I would certainly try what you're suggesting with TMPGEnc - it shouldn't take long to demux and then mux in an empty audio stream to do a test. I've used TMPGEnc to create program streams for DVDA 2, so I know that part works.

In DVDA's explorer, right-click on the file and choose Properties. Copy what's there and paste it here so we can see the file's details.

This works in DVDA 2. I'm not sure if the same function is available in DVDA 1 as I only discovered it recently. If not, then just click once on it and see what it says at the bottom of the window -- it should list the file's basic video and audio properties.

Thanks Scott, one more question:

I didn't realize the rerendering problem until I had set up my title page and inserted chapter points (thankfully there's no chapter menu). Will DVDA gag if I simply try to replace the original project assets with the TMPGENC video & audio streams? If so, is there an easy way to transfer over the title page text etc and the chapter points to a new DVDA project?

Thanks again.

These are the file's details, cut and pasted from DVDa:

Streams
Video: 01:29:34.869, 29.970 fps interlaced, 704x480x32, MPEG-2
Audio: 01:29:34.896, 48,000 Hz, Stereo, MPEG Layer 2

There's the culprit. In DVDA 1, 704x480 was not considered a DVD compliant frame size. As of DVDA 2, it is allowed. Who knows, maybe DVDA 3 will allow even more frame sizes.

Edit: Oh, and DVDA doesn't like that the audio is MPEG, but that's not too big a deal; audio doesn't take nearly as long to re-render as video does.

So, if you're sticking with DVDA 1, there's no point in demuxing / remuxing your file in TEMPGEnc; what you need to do is change it to 720x480. Or use DVDPattcher to try and fool DVDA (a much quicker, simpler solution though it might not work).

Thanks, Rob, I appreciate your help. I guess I'll just let DVDA re-render.
