Could you check with task manager if the CPU load is happening in kernel or in user mode?

1) set View -> show kernel times
2) open performance tab and check the kernel side usage (red line)

It could be DVB card's drivers. If the kernel time is not high (only few %) then please try disabling the EPG grabbing completely.

 

I've been getting this too. For me, the "System" process goes to 100% utilisation (on one core), not the TV Service. When I check what is causing this using process explorer, it's the tv tuner drivers that are responsible. Killing the TV Service usually restores things to normal.
This doesn't happen every time, but there seems no pattern to what causes it. Next time I'm at home when it happens, I'll update this post and add logs. It seems to happen around two times a week for me, but this also seems to depend on how much I'm recording TV at the time. It's hard to find firm patterns as it's not often enough to establish a link.

At least this may help isolate that it's something to do with the driver interaction.
I have two tv tuner cards. Both DTV-T. One is a DVico, dual PCI and the other is a DNTV dual PCIe card. The issue seems to happen with both, as I can totally remove one and the issue occurs. Then I reinstall it and remove the other and the issue is still there.
I've reinstalled Windows since and the problem persists. Until I read this post, I figured it was something to do with my installation as no one else seemed to have this issue. I was planning on going Windows 7 soon to see if that would help.

Anyway, logs will come soon, but I didn't see anything relevant in them when I looked a while ago.

Normally that means bad drivers, as applications itself aren't running in kernel space. But it could be something in TVE3 side that gets stuck in a infinite loop and queries the driver constantly. I would suspect DVB EPG grabbing, so try disabling it first and see if you are still able to reproduce the issue. It is much more likely that the EPG grabbing would have such issue. Recordings are accessing the DVB HW (not directly, but thru the directshow filters from OS) only when starting and stopping the recording.


After looking at the logs in the other thread (recording failure):

I would say that driver is not working properly as the graph cannot be started. I did have similar issue when my Floppy DVB-C was starting to die.
