I think you're going to want to produce a VCD or SVCD rather than a DVD. Don't think DVDA does this. Vegas will burn a VCD right from your timeline, and I've had them play on every player they've been on. Nero will do the same with a Vegas *.avi file. DGrob
You can do this, but your set top player is unlikely to play it, though there are supposedly a few set top players that now support this format. It's called a mini-dvd, and it's not recognized as an official format (afaik). Most software players can play back this format though.
As mentioned in the other reply, you'd probably have better luck with a VCD or SVCD.
I did quite a few Mini-DVDs before i got my DVD burner. I prepared the disc in DVD Architect, then used Nero to burn to a CD-R. I had pretty good success playing them; just about every player i tried that was less than a year old played them with no troubles. The players that seemed to have the most trouble were those costing over $250. The $40 cheapies all accepted them happily.
For maximum potential compatibility, keep the bit rate under 3500Kbps. The bits are bigger on a CD-R than on a DVD-R, so they can't go by the laser as fast. If you burn at a higher bit rate some players simply can't read the data fast enough.
