SageTV CPU 100% when recording

[manueljben]

Hi ppl...

I've installed a couple of days ago the brand new release of SageTV 6.3.5.

I have two Hauppauge cards, one is 350 pvr and another is 1300hvr (which is DVBT capable). I have DVB-T disabled at now, due many problems with older versions of SageTV, segmentation faults.. etc

I can record two shows at the same time, one with each card, but usually i record only one, and my "primary" card to choose for record is the 1300hvr one.

With SageTV 6.3.5, recording from the 350pvr everything goes fine as usual, used cpu is around 4% and i can watch a recorded show while sagetv is recording the new one in the background. But when recording from the 1300hvr, CPU usage raises nearly 100%, and the UI is almost unusable, because changing from one menu option to another takes ages .... (when you watch the recording from that card, the video isn't smooth.. i think it is due high cpu usage when recording, which causes a lot of frame loss)

Any ideas? Thanks in advance.

PD: I've (re?)installed the latest Hauppauge drivers with no luck. My system is a Windows XP SP2 up to date, dedicated to HTPC with no 3rd party software like antivirus.. only SageTV.

I can't believe nobody has this issue or similar ?! No fix?

I'm not familiar with the HVR1300, but I'm guessing it doesn't have an onboard MPEG encoder. Many analog/digital hybrid cards do not. That means your CPU must do the encoding when recording analog TV from this card. High CPU usage is normal in that case, but exactly how high depends on your CPU, which you didn't specify.

The PVR350 does have a hardware encoder on board, and that's why its CPU usage is much lower. You should use that as your preferred encoder for analog TV, and reserve the 1300 for digital TV (which does not require encoding).

1300 HAS an mpeg2 encoder on board, at least that's why i bought it.
HVR-1300 (HVR -> Hardware) lower cards such as the 1100 in the box says PVR..

But related to the thing you said, HVR1300 was recording fine in Sage 6.2 both digital and analogue, even while the PVR350 was recording also, and the CPU level IIRC was always below 15% approx.

When I installed Sage 6.3, then I have this issue (in Sage, of course. In WinTV everything goes ok)

Thanks for your help!

So if you roll back to 6.2 does the problem go away? Had you tried any of the betas before 6.3.5? Did you have the problem with them? If so then it's a Sage issue with the card and you should submit a support request. Which seems most likely in this case.

You could also check the tuner setup, the hybrid cards have a lot of tuner options during setup, if you got the wrong one or something in 6.3 changed it somehow it could cause problems, but that's probably a long shot.

There is a bug with the software encoder in the 6.3 releases. Support has been working on this they have sent me several files but none have worked. The 6.2.10 release works fine. If you are not using one of the new HD extenders I suggest you stick with 6.2.10 on the server... you can run the new 6.35 clients with it.


manueljben..... file a bug report.

Glad to hear that, I was becoming crazy trying to figure out where the problem is.

As Djc208 also said before, I'll try to rollback SageTV to the 6.2 version...

Thanks to all for your responses!
