There's no such thing as a 1.304 DAR in MPEG encoding. If he imports the MPG files directly from Mpeg-VCR they should have the correct DAR flagged.
The MPEG 2 spec only has three defined display aspect ratios: 4:3, 16:9, 2.21:1 and square pixel PAR.
Well OK, it's possible to have a 3.04 DAR with square pixel encoding and the appropriate frame size. I don't see how AVStoDVD can be getting the DAR wrong with a 352x480 frame size. Unless MPEG-VCR is adding a sequence_display_extension with the wrong values.
The OP should upload a small sample of his MPEG-VCR files.

MediaInfo to read video and audio info. I don't know if that is a MediaInfo bug or a badly muxed mpeg2 file. I agree that a short sample from the OP could help.
BTW I have already received some 720x480 mpeg2 flagged as 1.5...
Here's a sample 10-second video clip.
About the short sample (Mediainfo report, advanced mode):
PAR (pixel aspect ratio) = 1.778
FAR (frame aspect ratio W/H) = 0.733 (352/480)
DAR (display aspect ratio) = PAR x FAR = 1.304
To be 100% DVD compliant:
PAR = 1.818
FAR = 0.733
DAR = 1.333
The trouble is with PAR that is just a little smaller than the NTSC Half-D1 4:3 standard value (1.778 vs 1.818).
With the workaround I have explained before, you should fix it directly in AVStoDVD.
Yes, the video has a sequence_display_extension that indicates the flagged 4:3 DAR is contained in a 360x480 frame. Since the data is actually only 352x480 the display aspect ratio of the available picture is only ~1.304. Ie, 4 / 3 * 352 / 360.

I downloaded the latest version and followed your instructions and now the title output size is good. It is 605MB. Thank you!
Now, my next question is:
Every time I add a title I get the message that MPEG2 video stream is found and that it is strongly recommended that I index it.
Press yes to create index and demux the audio.
My question is: Do I have to do this? Thank you for your help. Ron
Thanks to everyone for your help! It's working now.
