This past weekend, I've been ripping and encoding of lot of my new movies to play on the TouchPad -I had already a ton of older movies, but was no longer doing so since I've been using the Netflix app on the Evo 4G.
However, I'm don't remember if that was always the case, but using Handbrake's defaults (iPad settings) always got me great results. But this time, not with the TouchPad.
The files being created by Handbrake had the .m4v extension (h.264 encoded, as usual) but they would not play on the tablet. I then decided to change the extension to .mp4 and voilá! Fixed!
Anyone else having similar issues? What's the file extension (and encoder) you're using?
