Having a problem playing back AVI files on a PC that uses my Plasma as it's monitor. I have the settings set to 800x600. I am using KMPlayer to play the AVI's. They seem to ages to start to play, and play fine for a while, then the screen seem to stop/start intermittently. Then freezes. If I re-boot, it goes OK for a while then plays up again. I have NO Graphics card in the PC, and there is no PCI-e or AGP slot. But i do have a 2 x PCI slot's available. If i purchase a 32/64mb PCI graphics card, would be likely to solve the play back issue, or am i throwing $$ at the wrong component? The PC is on a small home network, and is playing the AVI's that are stored on an External LAN HDD. I though maybe the cable length(20mtrs) was too long to transmit the data for the speed of play back, but even a AVI on the PC itself, does the same thing. Thus me, thinking Graphics issue ? Any advice on what to look at to solve this ?

If the system described in your heading is the one giving the problem the answer is there. You are running XP on a system with only 256mb ram and some of that is shared with whatever onboard graphics card your motherboard uses. You will definitely benefit from getting some additional ram. Double your present amount as a minimum. Since you have an available PCI slot you should also investigate getting a PCI graphics card with say 128mb of it's own ram. Finally Check to make sure you don't have too many programs running in the background. XP runs a lot of processes continually and some may not be needed.

Thanks for the reply. I will look at some more RAM. There is only an Antivirus (Avira Free) running apart from what XP runs.
