Optimal Video: Pixel Resolution, Bit Rate, Format? Sony Vegas Movie Studio

[1up]

DLCPhoto I would be interested in your exact process in rendering from Vegas. There are 2 different options for rendering .mp4, Sony AVC and MainConcept AVC. Both of these create files that crash TCPMP and don't play in Album or Media Player. I've tried exporting H264 MP4 out of Quicktime, but when played on the phone all I get is audio if anything at all...
