Since I got my lcd tv I've noticed that during dvd playback, when the camera pans fairly quickly, movement is actually slightly jittery. The jitters seem to be fairly regular. I'm not sure what is causing this. Any ideas? One idea I had is that there some kind of mismatch between the refresh rate of the dvd, the refresh rate my graphics card is outputting (60, though I could try 50 or 59), the refresh rate that works best over hdmi, or the refresh rate that my tv prefers to display. I don't know. Should I try and force my video card to output 24Hz and see if that makes a difference? Just a noob guess, and I don't want to make my tv 'splode :)
Currently my specs/setup are as follows:
AMD Phenom x4 9750
Sapphire Radeon hd4870 (outputting both audio and video via one DVI port with a DVI->hdmi dongle and an hdmi wire attached).
Some kind of SATA DVD-RW drive. I forget specific model (perhaps pioneer?)
Windows Vista Home Premium 32bit.
Windows media player (Haven't tried or even installed power dvd or VLC, I guess this would be my next step).
