Terribly sorry if this has been covered, but a search didn't yield anything for me. I have a secondary machine hooked to my tv in the main room. It's a bit dated:
4gig ram (just typical generic ram)
500 gig seagate sata hdd
Asus mobo, (the exact model escapes me atm.)
win 7 pro x64
Anyhow, I've basically turned it into a media machine for the large tv in the main room. As long as I use power dvd and play straight blu ray stream everything is fine. However when trying to playback avi/mkv/mp4 in kmplayer/media player/vlc etc.. of any quality level I get stuttering and pixelation, that gets drastically worse when the mouse pointer appears on the screen.
Furthermore I've noticed a very slight...almost lag related to the mouse pointer even when video is not playing. I've killed almost all the appearance settings in an attempt to figure out what the problem is with no real change in performance.
I've also made several attempts already at fixing any codec issues that might be there, including buying the coreavc codec to make use of the nvidia cuda that is supported by the card. I also played with bringing down the number of running processes both in system management and with msconfig (Startup)
...anyhow any input or further ideas would be welcome.
...oh and hi... I'm new here. I have a fair understanding of computers, build my own systems minor oc'ing, basic software troubleshooting etc.. this one just isn't making much sense to me.
