SageTV on Windows Server 2003, high cpu after video capture

[HeeZy]

i decided to try SageTV 6 on server 2003 with WinTv-PVR-USB2. when i set up a timed recording, i then use the service to record it for me in the background. i open up process explorer to view the cpu usage of the service and after the capture finished, cpu usage sky rocketed to a constant 88%.!! this was happening for several minutes.

i double clicked the service process and noticed that a file called ksproxy.ax was eating up the cpu time. here is what the thread was called,

ksproxy.ax!KsGetMediaTypeCount+0x30af

i googled and found out it was a directx file used for video capture, but i don't understand what GetMediaTypeCount is.? whatever it is, i don't want it to eat up cpu time. i also have the latest directx 9.0c installed.

i tried it out in XP Pro and after a capture, the ksproxy.ax thread also came up, but only used 1-6% cpu time, which is good.

so does anyone know why it uses all that cpu time after a capture and how i can stop it, or reduce the load?


thanks.

Did you download and install DirectX on your Server 2003? I don't think it is there by default.

yes i downloaded directx 9.0c and installed it, rebooted. but still get high cpu after a capture. i'm still trying to figure this out.

i read about a fix to use dx9.0b setup files when installing 9.0c. i'll have to try this out.

EDIT: tried, but to no avail. still get high cpu usage after a capture.

Heezy,

I know this thread is ancient but did you ever figure out what the problem was? I'm getting the exact same issue on my new Win2K3 SageTV Server (it's a virtual machine) using a WinTV-PVR-USB2. I previously had SageTV Server running on a physical box with Win2K3 and the same tuners without any problem. Perhaps a reinstall of Sage and/or a switch to XP is in order.

The one other interesting tidbit I can add is that when SageTV Service is stuck in 100% CPU usage on ksproxy.ax!KsGetMediaTypeCount if I start the SageTV Client on the same box it somehow snaps out of it and begins operating normally again.

Any advice would be appreciated!

Thanks.

no, i never found a solution to this. i just gave up switched back to WinXP.

Thanks for the update HeeZy. Maybe I'll follow suite and try out an XP virtual machine as my Sage server.
