The problem most likely is that the audio is at the wrong sample rate. The TiVo samples at 32kHz, while DVDs tend to prefer 48/96kHz sampling. (32kHz is an "odd" sampling rate in the scale of normal things, but it's the best for broadcast quality audio).

yea. vcd help is great.. lots of articles they just posted a new one how to get 450 min of video on a dvd 4.7 gig..

Standard DVD support MPEG1 so it is possible to author VCD MPEG files to DVD, on one standard 4.7 DVD-R,DVD-RW or DVD+RW disc you can store about 450 minutes VCD MPEG. But the DVD standard requires 48 khz audio(VCD is 44 khz) so it requires some preparation before authoring and burning the DVD.

I also endorse Ulead Movie Factory. I've been extracting mpeg2's from my replay 4080 and it works great for burning them to DVD-R (or VCD if I re-encode the file! I'll be trying it shortly with video extracted from my tivo. Never did get the MyDVDit that came with the A03 to give me a decent disk. Only drawback is the menuing system it generates is very basic.

To edit mpeg2's I recommend Womble. Other editor's I've tried screw up the audio sync but Womble (Mpeg2Vcr) does a great job of editing the commercials out and keeping the sound synched.

Ulead will accept a 352x480 mpeg (which is what I encode all quality levels at) so long as the audio is 48khz.

DVD factory uses takes the muxed mpg as an input (although Im pretty sure the software demuxes and then remuxes in the DVD compilation steps)
