[mythtvnz] HD Video jerky...

[Douglas Pearless]

I agree,

Go for a GT220 card PCIe (requires a x16 slot), if you only have PCI / AGP then it is time to upgrade the motherboard; your CPU should still be OK (I notice there are some PCIe x16 motherboards with CPU on trademe for under $100) as most of the work is done by VDPAU (don't forget to select the correct profiles in mythtv in order to enable support!).

Cheers
Douglas.
