USB-UIRT XP drivers lead to high CPU usage in SageTV

Postby krasev » Mon Apr 28, 2008 5:39 pm

USB-UIRT XP driver ( UUIRTDRV.dll Ver.2.6.9.8 ) causes high CPU usage in SageTV. Here are the picses from Sysinternals Process Explorer.

Usally this happened when SageTV service (SageTVService.exe) on your machine already running recording smth and you are trying to open your own client (SageTV.exe). USB-UIRT XP driver thread running on SageTVService.exe without any high CPU, but starting SageTV.exe activates another threads of UUIRTDRV.dll with high CPU usage.
Eventually I figure out the cause of high CPU which troubled for so long. At least now I khow the cause of it.
Any idea how to troubleshoot this except just to rewrite drivers for WinXP?

Well... playing with it I found kind of solution...

in SageClient.properties file (properties of SageTVSevice.exe) I left as it was:
---
ConfigWiz/Remote=XUSBUIRT
---
and in Sage.properties (properties of SageTV.exe) I changed it to:
---
ConfigWiz/Remote=XNone
---

sure... in order USB-UIRT works you have to run both Server and client... if you don't use server I think there won't be second tread of UUIRTDRV.dll activation anf no high CPU. So ConfigWiz/Remote=XUSBUIRT should be in Sage.properties file.

after these editings no high CPU running client and server together
