Encoding MPEG2 at hi rez?

I've mostly used Xvid & DivX but wanted to try encoding some sample MPEG2 HDTV clips at high resolutions, say up to maybe 1920x1080p. I just wanted to see how playable they were with the hardware MPEG2 accel support built into some graphics cards.


Both TMPG and CCE appear to have limitations here. Anybody know if there any other free/cheap/trial encoders that can handle something like this?
