Jerky Media Playback / Skipping Frames

[carlty]

Please Help!!!!!

I have read similar problems but not quite the same thing in other threads.

My system is as follows:
MSI K9MM-V MoBo,
AMD Athlon 64X2 3800+,
3GB RAM,
On board Shared Graphics Card

I bought Windows 7 mainly for Media Centre, as my desktop PC has been my TV, DVD player, MP3 player etc for the last few years. I was running XP and upgraded last weekend to Windows 7 Home Premium 32 bit.

I noticed first that the TV playback in WMC was skipping frames and very jerky, but then I realised that this was only in full screen. When I play it in a smaller window it is fine, then when I go fullscreen it is fine for around 20 secs, then a flicker happens and the problem starts again. If I change the channel, again it will be fine for some seconds, then same thing again.

I have noticed now tonight that when I playback movie files in Media centre there is the jerky frame skipping, but in Media player it is fine?????!!!! Also alot of times that I play either TV or Video files in WMC the screen is just full of lines and I have to close it down and reopen, sometimes several times in a row.

On top of this I've now realised that when I was watching online TV (Flashforward on Channel 5) the frame skipping is there too (Explorer 8).

Could this be to do with the onboard graphics? I thought 64MB was fine for windows 7.

Please help before I have some sort of fit from watching this jerky TV!!

Best thing you can do is to make sure the tv card, chipset and integrated video drivers are updated to latest possible.

Also, when watching tv, it's best to ensure nothing else is trying to use too much of the cpu since it is rather old by now.

Thanks torrentg - those were the first things I did to try and resolve it. The only other thing I have running is the antivirus (AVG free). I haven't even installed any other software on it yet.

Ah. Not for nothing, that AVG has caused more assorted issues for people than I care to mention.

Try completely uninstalling that to see how things go.
