Hi There
I just purchased Tv tuner hauppauge prv150 MCE ,and I would have thought this hardware would resovle any older TV tuner inconvenient.After have to play many hours and compare to my old Tv tuner which had no hardware mpeg-2 encoder finally I realize this new product need too much CPU while playing with Media center XP ,my PC is Athlon 64 X2 Dual Core 4200+ 2.2GHz with 2g of Ram .It consume between 30% to 40% of CPU while running with this PVR 150 MCE ,contrary to my older TV tuner chipset 7130 by Phillips it consume only from 4% to 6% of CPU ,it will consume about 35% of CPU if recording a TV with MPEG 2 compression.I had running both TV tuner at the same time the same channel for comaparison a picture quality ,my older TV tuner has better detail and sharp picture than the PVR150 mce ,moreover the picture tv of PVR150 mce display around 1.5 second later than the old Tv tuner due to the complicit of mpeg2 encoder and decoder .Here is a fonctioning of PVR 150 mce : Convert ANALOGE signal to DIGITAl and encode to MPEG2 output to CPU ,then CPU need to decode MPEG again to display on screen ,That why this procedure of a new TV tuner hardware MPEG 2 encoder has to consume a lot of CPU .My conclusion prefere the older tv tuner without hardware mpeg encoder
