1) I've gathered, x264, xvid, real, badaboom, wmv, ffmpeg, nero, quicktime, vp7, elecard.
2) Well x264 is easy with presets. I'll probably stick to veryfast, medium, veryslow. With tune psnr and tune grain. It would be nice if you could provide a visual quality setting.
I'll need suggestions on settings for other codecs!! I've only just installed them.
3) I'm thinking, park_joy, rush_hour & something from star trek (blu-ray) - all resized to 720.
