I have a machine running mythbuntu that has reasonable specs
Athlon x64 4200+ cpu
1GB ram
nVidia Geforce 7 video card
500GB sata hard disk
and it runs very well, can record 2 HD TV programs from my 2 DVB-T tuners and playback at the same time.
One small glitch happens, however, when watching a scene that pans very quickly through a scene. I guess this is the hardest thing for the video to cope with. What happens is that about half a dozen horizontal glitches appear across the picture. They aren't lines or noise, just more like discontinuities in the picture, as if the half dozen bands across the picture don't quite all pan at the same time in sync.
They only exist while there is panning motion, and if part of the picture is stationary (like a shot of someone in a car with the scenery going past outside) then the lines are only visible in the moving bits.
It's only a little bit distracting, but if there was something I could try, - maybe a setting I can tweak, I'd like to see if I can get it perfect.
Of course, it MIGHT be being caused by something outside the myth box, like my flat panel TV which is being fed by a VGA input from the mythbox, and so is upconverting the video to it's native resolution on the fly.
Anyway - any comments/suggestions are welcome :-)
