I would suggest you use AC3 all the time. AC3 is very good and it’s very difficult to detect the difference between it and PCM. In addition, PCM takes up about 8 TIMES the space of a typical stereo AC3 track. For 2 hours of video (a typical amount to try to fit on a standard DVD) PCM would need almost 1.4 GB of the 4.7 GB total. AC3 would take up 176MB. I’d rather have those extra 1.2 GB allocated to the video.
As always, YMMV.
Good luck.

Indeed. All copy protection mechanisms only protect against direct digital-to-digital copies. If someone desperately wanted to copy your DVD all they would need to do is play it and capture the image with a capture card or box. Sure, it will be lower quality but it may be good enough for what they want.
Good luck.

I don’t know if it’s too late and at the risk of getting my head handed to me: if the client wants 4:3 you should shoot 4:3 and avoid all these problems.
As I said, maybe it’s too late; maybe you cannot go back and reshoot or you are working with previously shot footage. But, frankly, I’d avoid all the high tech solutions. Sometimes the technology gets in the way. I’d try to shoot in the format that the client wants in the first place.
OK, I’m ready for it. 😉
Good luck.

When you add assets to your DVD project DVDA shows the estimated size in the lower right corner of the screen. It’s labeled “Disc Space Used”. I think it is often overestimated. The best thing to do is use a bitrate calculator so you can figure out what settings you need to get the desired size before you go into DVDA.
Good luck.

If you have titles and other generated media it is best NOT to render to AVI then reload and encode to MPEG-2. Rather encode to MPEG-2 directly from the timeline. You’ll get better quality on the generated media since it is represented in 4:4:4 color space within Vegas. If you render to AVI if is converted to 4:1:1 or 4:2:0 depending on whether you use PAL or NTSC. I.e., you are throwing away some of the color if you render to AVI first.
Good luck.

Could it be your display monitor?
Good luck.

If the video on your DVD is longer than 1 GB’s worth of MPEG it will be split into 2 or more VOB files. You will need to collect them all and add them to your timeline to get the complete video.
Also, be aware that when the DVD was created the video was compressed and some video quality was lost. If you encode to MPEG-2 a second time to create another DVD you will be lowering the quality even further (think a photocopy of a photocopy). I bring this up because you said it was 1940 vintage film so the quality may not have been that good to begin with. Just so you know to keep your eye out for the quality.
Good luck.

The word is actually “demultiplexing” (the opposite of multiplexing) but a lot of people shorten it to “demuxing”.
Good luck.

I’ve also seen DVDA2 overestimate the size of my assets when authoring a DVD. I knew it would fit so I closed DVDA and reopened it and it said everything would fit.
Good luck.
