DVD SIF format

I want to author a DVD with SIF format video. I have captured seveal home videos converted to DVD-SIF format (352x240 MPEG-1 video, 48KHz audio). Each 30-minute video is about 280 MB. I have tried importing them into DVDA V2 and it reports 1.8GB used for each 30 minute video clip. This is wrong. The DVD standard SIF format should allow almost 6-8 hours on a single DVD! I have tried both interlaced video+audio (.mpg) and separate streams (.m1v+.mp2) and neither work right.

I tried changing the project properties and optimize properties to 352x240 and pcm audio and reduced the bitrate to its minimum, but that doesn't seem right. I dont want it to re-encode the videos to MPEG-2, they should already be in a DVD-compatible MPEG-1format.

What am I doing wrong?

DVDA produces DVDs with MPEG2 only, not MPEG1. If you give it an MPEG1 file, DVDA will re-encode it to MPEG2, and unless you change the default, it's going to do so at 8Mb/sec. In addition, if you didn't change the project settings from 720x480 to 352x480, DVDA might be planning to resize the video as well. Check your settings. In DVDA2, you can have 352x480 video, but you'll have to use something else if you want them to stay MPEG1 format.

This is a very expensive program to not support ALL of the DVD standards. In my case, my source videos are not very high quality, so it is silly to author them at Full-D1 or even Half-D1.
