Athlon 64 3000+ 512mc pc3200 Samsung Spinpoint 160 MSI RS 480 M2 Motherboard On board sound & graphics. Pioneer 109 DVD Nebula PCI Digi TV Card When playing DVDs or watching digital tv I have noticed a very slight stuttering of the image compared to watching tv direct with an analogue signal. It is most noticeable when titles or text scroll across the screen. I thought that maybe the onboard graphics were not up to standard ( said to be the equivalent of an ATI x300 ), but having talked to a company that specialises in HTPCs they claim this problem is inherent in playing video through a pc. They have tried using high end graphic cards but still get the same problem. Does anybody manage to get completely stutter free video through there HTPC ? Its barely noticeable, but I would still like better video playback if possible. Many thanks.
