There were some people who were playing around with resolutions based off of 1080i instead of 720p. You will probably find the threads by doing some searching here and in the HTPC forum. As to going past 60 Hz I doubt it will be possible. The only way we can get wide screen is tricking the 10HT to think we are giving it a HD signal, all of which at 60 Hz. If you don't mind 4x3 you can boost the rate up by putting it in Comp mode.
I'm not sure who mentioned it but... the refresh rate thing might be a moot point anyway since there is a good chance that whatever refresh rate you send it gets resampled to the native refresh rate of the panels anyway.
