How many channels and days of data do you guys have, and what capture devices are you using?

About 20 channels, no EPG for the moment, since I (yet) don't have internet access after the move. PVR-350.

Can one of you that has this problem try setting the logging level to 'Info' to see if it helps? I'm wondering if the fact the log file is actively flushed to disk if causing the problem.

For laughs, try opening and closing the CP to shrink it, or user compact and reapir using Access if you have it. Then see how it does.

Mine is usually <100Mb on avg. I think <80mb when I compact it.

I take that back..I just open/closed the CP and gbpvr.mdb is 5Mb. That's a much smaller file to communicate w/, even when you're just getting a last modified date from it.

It doesnt actually have to read the file to get the last modified date from it. It shouldnt matter what size the file is.

I only raise it from behvior I see doing web programming. It may not have an impact the way you're dong it, but I can see a longer response time getting just file details from larger files than small one. It's only perceptable because of the number of files and natural delay from a remote connection. If it were local, you may not notice the differnce.

If something were also monitoring file inquires (eg, antivirus or system state monitors), it would also add time to the reposnse that you normally wouldn't even notice.

Again, just offering possibilities that may not matter at all. I find it helps to entertain any possibility when you still don't have an answer, no matter how unlikely they may be.

I tried changing the logging info and it didn't seem to make any difference.

Like I noticed before, it seems to be tied to the size of the EPG (stored in the Access database). I used the program FileMon.exe to record file access while "Time Shifting" and every 30 seconds there is a lot of access to the gbpvr.mdb and gbpvr.ldb files. I don't know what they are doing just that they are doing something. Hope this information will help.

The entries in the logs appear at times 2:19:02 - 2:19:03 and 2:19:33 - 2:19:34.

120 channles, only 5 days, file size minimum after compress about 6MB. I get the stuttering in timeshift and 100% CPU spike even at this size. If I don't compress every few days the EPG and webadmin system become virtually unusable.

Can some one run a test for me? Bring up GB-PVR timeshift tv, and the Windows clock on the desktop at the same time, then note the exact times the problem occurs so we can compare with the times in the log to check if it precisely maps to the "RenewLease" activity.

Let me know if it does precisely coincide with the renew messages in the recording service log, and we'll go from there. It seems likely it would coincide with these, but I want to be sure.

Can someone please time the frequency of these small jumps in CPU in the task manager or perfmon? Is it really every thirty seconds, or did it just seem like thirty second? Before you reply "yes, its every thirty seconds" time it - dont guess.

I was curious after reading all this ... and i checked out timeshift mode.. i waited for my first spike ofr 98-100% (lasts about 2seconds)and used my watch and counted 29 seconds before it happened again .... and it repeated 3 times before i got bored and stopped.. ( btw this is counting not no atomic exact stuff)
But it does spike cpu usage.. just to confirm.
EDIT: i dont get any picture lag from it unless im doing something else at same time too..or its extremely active scene of a show.
Also .. did anyone else notice if your watching tv with gb-pvr and you right click any media like music file and it shows the open properties and rename stuff.. it freezes /skips up gb-pvr... why?
