No, that's not it either (20MB/s). That would also mean that everybody 
having this problem would have slow CPU or slow HDs which just isn't the 
case. I've had other mythtv/ivtv/via-drv combinations work more or less 
perfectly, it's just the current combination that isn't working for me.

Just to make it clear: I'm not complaining, just stating that the 
current combi isn't working for me, but I'm patient and will just wait 
until everything works ok again and maybe even help where possible.
