Hello I have experimented some more with the card, including the following: * Putting into another computer, MSI motherboard Nforce 4 ultra chipset with an AMD Athlon64 3500+ * Adjusting the PCI latency timers to various values * Cooling down the card by directing a fan at it (I noticed the on board mpeg encoder becoming very hot)
these tries were all unsuccessful. To be absolutely sure to rule out any hardware malfunction, I rapidly installed windows xp. *boom* it appears it doesn't suffer from this video stutter under windows! So it's either linux or the ivtv driver. Any suggestions would be appreciated. Thanks Glenn RedShift wrote: > Hello ivtv'ers > > I just got a hauppauge WIN PVR 350 working with ivtv 0.7.0.
