Jerky DivX on TV-Out

[AwesomeDude]

I often encode dvds to divX using Gordian Knot and they play fine when I use my monitor to view them. However I bought a graphics card recently partially so I could use the TV-Out function to view my DivX movies on my TV. However, although it works, the video becomes quite jerky and sluggish after about 3 minutes of viewing time. My graphics card is a Sparkle G-Force FX 5200 AGP. In fact, it doesn't just happen for DivX, but pretty much any video files, DVD's and all. I live in europe and my TV is therfore PAL.
Anyone have any ideas?

If you use both the tv and monitor at the same time is it only jerky on the tv?? or both. Try also tvtool.

Hmm....I have a 5200 in one machine and the TV-out is perfect (its the same TV-out as the higher level cards).

Is your psu (power supply) on the way out/on its limit or is your pc overheating?

Yeah, if I play the videos simultaneously on the monitor and the TV, only the TV is jerky.
