That's with mythtv and the 180.25 driver. It could be a driver or application issue, but I suspect the hardware can't manage it.
Other than that, it has played everything I've thrown at it (13.5 Mbps h.264, vc-1, and so on) with ease while still handling the mythtv OSD smoothly.
For $29 after rebate I could not resist the urge to pick one up. Should be here Monday
Have you tried a bluray (or HD-DVD) rip using the internal mythv player? Or do you use mythtv to launch mplayer?
