It seems that the disk throughput is the problem. I get 20-66 MB/s when 
watching TV, as measured by "hdparm -tT /dev/sda" whereas others get 
200-300 MB/s. I get that much when idling only. No XvMC, and CPU is 
consistent with what others get (I am not at home right now.)

There is pretty much nothing I can do to tune a SATA disk in Linux. 
hdparm, sdparm and blktool can only read values for SATA, not set them.
