I've tried rendering both MPG 1 and MPG 2 and have been using these files in DVD Architect. The MPG 2 doesn't even put the audio on the program, the MPG 1 has audio but it cuts out after 1-2 seconds on each clip. What could be causing this?

It did this when I was previewing the DVD as well, though I figured it'd work properly on the DVD.

I'm rendering it as NTSC 720 by 480, AC3 audio. I'm trying it again with AC3.5.1 surround.

I'm new to this (you can probably tell), so shoot my way even the most elementary of solutions.

Thanks in advance,
Jake
