Windows 7 Media Center -

If I change the channel or if I am watching a video and either move forwards or backwards in the video the image stutters and goes into an infinante loop of 3 seconds (i.e. the picture seems to jump back and forward amongst 5 or so frames just repeating - audio fine).  I have to push stop and go back and chose the channel again - and then it works.  Sometimes it happens if I skip back and forward in a video played in media player.

THat leads me to think its a .wtv problem.

I have a 2.2ghz core 2 duo, 3gig ram, 256mb Geeforce 9800se.  USB Avermedia Twinstar (2 tuners one USB) on my laptop. 

Video will usually (if I dont do anything) play fine. So i dont think its a processing thing.

Does anyone have any smart ideas for me? At my wits end.  Thinking of taking this card back cos it wont do what I bought it for.

(finally got the EPG working after installing guidehound - not stoaked at the prospect of having to pay for it tho if I keep using it as the USB tuner was advertised as being EPG capable - NOT COOL PB TECH)

So if anyone can help me fix my stuttering/freezing/skipping (I dont know what to call it!) problem that would be AWESOME!!!

cheers
