I have just installed Peppermint Six instead of Mint 13. When I use VLC videos stutter (either DVD or from file). I suspect is it s driver issue, but I am relatively new to Linux, so advice would be appreciated (other than returning to Mint 13!).

I also noticed that Xorg started using 98-100% CPU when trying to play a video.

I also post inxi return in case it is useful.

Thanks

I fought with "stuttering" for months,... but mine was evident whenever playing .flac -- via Audacious, Banshee, VLC -- no matter,-- after a while the stystem would start to stutter-- I called it "The Jitters" : response to inputs -- particularly mouse signals -- was always lethargic . my Firefox was lethargic attempting to scroll.

I have now switched back to using a Behringer UFO202 USB connected DAC . since the switch back the stuttering has not re-curred . I have not reverted to the on-board DAC to try to recreate the problem; to get a positive on the culprit,-- but: I am also using an ASUS motherbnoard ( M5A88-M ) with the on-board Realtec DAC

system now works fine with either pulse audio or with ALSA

the Behringer can be had at Amazon for about thirty bucks

Sorted problem by installing propritory driver from Software Manager, having found which driver to use from nvidia webpage.
