I have my TV connected to my PC via a DVI->HDMI cable.
My PC monitor is connected via DVI>DVI, and via the Nvidia graphics settings, I have just set the TV as a slave monitor, I.e whatever is on the PC monitor is just mirrored to the TV.

Graphics card: Nvidia 8800GT 512MB

PC resolution: 1680x1050 (22" LCD)
TV Resolution: 1680x1050 [Mirrored from PC] (32" "HD" TV)

Audio is connected via a audio headphone splitter (1 into 2) with a lead to PC speakers and a lead to the TV inbuilt speakers.

When playing a film via VLC media player. 701MB, Video total Bit rate: 117kbps. 23 frames per second, I get scan line sort of things that scroll up the TV from about half way to the top, it happens about every 15 minutes.
(Video resolution 596x246)

Is there any way to stop this, some kind of buffering system?

Any help is appreciated, thanks;
Wigster.

Not that I know of.

I've been told it may be a ground loop?
This is how my TV/PC/Monitor are set up, and how they get the power.
