I noticed that watching live TV uses 95-100% CPU time using mpeg4
encoding at 640 X 480.  My system is an Athlon XP 1800 with 256M PC 2100
ram.  Running hdparm tells me that my hard drive throughput is about 23
Mb / sec.  Is this performance about what I should expect?  If so, what
would be the best way to increase performance, more memory, faster
processor or faster hard drive?

Thanks.
