    Actually it seems it's also available in mpeg2 as well.

    But for todays dual core, or quad core cpu, 40mb/s is not a problem.

    arggg!! single threaded, no way!!! it has to be multithread of course.

    Obviously if cpu is on load there is less room to encode video while watching. So nvidia wins here. Yes in geenral HTPC are more suited to video accel. But it is possible to play HD content on cpu too.

    I believe Kano has some information on how "big" bit rate 1080p can drain even a hefty CPU.

Even with modest 1080p content running on a MythTV box that is also recording four concurrent programs you are also more prone to problems than you'd otherwise be if GPU decode was available.
