There is a util on that page called "AVestensione" that can patch 480x480 mpeg2 files to make DVD Maestro (and maybe other authoring programs?) see the MPEG as 352x480, which is a valid DVD resolution. So maybe it is possible to author and create a DVD with SVCD resolution, even if it isn't technically supported. Now the only question is: can players play such a DVD and what would it look like? Stretched? Squished? Hmm... looks like some testing is in order...

UPDATE: Okay, I tried this. I got a PAL SVCD file and patched it with the AVestensione tool listed above. I had to re-encode the audio to 48 khz, but didn't re-encode the video, which had a resolution of 480x576 (PAL). I then imported the video and audio into DVD Maestro and made a short DVD, re-patched the .vob file Maestro output, then burned to a DVD-RW. Here are the results:

Software DVD players (WinDVD 2.1 and DirectDVD 2.5) Play the patched DVD perfectly! It is stretched to the full window!

Hardware decoders (Hollywood Plus and Netstream 2000) Play the patched DVD perfectly!

Standalone player (Pioneer 343) Recognizes the disc as DVD and plays it, but keeps the vertical resolution at 480, so it only fills 2/3 of the screen

Maybe the ifoedit guy can make a patch to have it fill the screen???

So the good news is...it can be done, but only if you play the DVD in software players or with hardware decoders, not standalones.
