System:
P4 2.4 GHz, 512mb ram, Nvidia 5000 series vid card

System was working fine with all previous knoppmyth installations. I did a fresh install of R5F27 to get a good start and now...

After a day or so, live TV and recorded TV stutters ever few seconds, but the audio sounds smooth. Downloaded videos (Divx etc) also stutter. Rebooting the machine fixes it, but after a day or so, it comes back. CPU is not really being used, happens even if it's not recording.

any help would be greatly appreciated, i'm a linux noob so please be clear with what info you may need or instructions. Thanks!

I am having the same problem, choppy video and sound on a new R5F27 install with a PVR-350 card...I tired the link for performance tips and none helped out...can anyone help?

Did you happen to install rrdtool for the first time?

If so you you might have a problem with mbmon.

no, never installed it, im thinking it might be the thermal grease on my CPU, as in the BIOS I see the Temp of my celeron D processor(about 1 1/2 years old) at 185 degrees F..which i would think might be the problem. So im going to move my hardware to another PC and see if a fresh install on it corrects the issue.
