as a matter of fact I have a couple of years ago. Didn't like it (don't even remember why) and stuck with XviD, which I'm really good with.
I do use x264 for my lossless pass with filters though.
I don't really see myself switching at this point. I'll most likely retire from releasing first. Being the only remaining ripper on the de facto undead ed2k network, it's probably appropriate that I use an outdated codec, come to think of it.
As for the movie: be warned, this sucks! Would have been a ShitBuster back in the day.
