WHS, demigrator.exe and SageTV.

[`ariel]

Hello everyone, i`m running Sage on my WHS (trial version) and have and Helius MVP to watch Videos and liveTV, everything is fine but when i`m watching some .avi and my server have to transcode it to play it on my MVP and demigrator.exe start running the video goes very bad, demigrator.exe consumes almost 80% of my CPU that's don't let any CPU cycles to the trasncoding process, any one with problem like this? my WHS has 1GB of RAM and a Celeron D 2.6GHz.

I have 2GB of RAM and a Pentium 4 3.2 GHz processor with hyperthreading. I don't see this issue. If you're transcoding you're going to want a more powerful processor. One like mine or a dual or quad core would work best.

I think the key is having a dual core like gplasky mentioned. I have an E7200 on my WHS/Sage box and I never notice any slowdowns. I should mention that I don't stream my DVDs off the WHS box - I have a separate Unraid server for that - but everything else runs off that box and no problems with the dual core.

I was afraid of that, have to change some hardware..... but if that is the answer it have to be done.
Thanks guys...

I've seen the same thing, but I'm not affected by it that much (Intel Core Duo 2.6 GHz).

Wouldn't it be possible to set the temp SageTV folder (mine is located on \\server\Videos\SageTV) to another drive that is not being affected by demigrator.exe?
Say something like c:\sageTV?

I believe the demigrator starts working because it's using space in the drive pool. Changing it to another drive could solve the problem...

The collective wisdom is right. Dual cores, at least 2 gigs ram. Best practices is a drive outside of the pool, 64k blocks, with a good ( non-ms ) defragger for the drive. With a good system, even the HP's with modifications, some people are finding this not necessary, but the reports of demigrator overwhelming the processor, even post PP1, are still coming in. Streaming is more ram intensive than processor intensive.

Yeah, definitely keep your recordings drive out of the drive pool. That's just asking for trouble.

i forgot to say, my recording folder is outside of the pool, when the transcoding service is doing his job, did he store the temp file in the same directory where LiveTV is stored?

I have my sageTV recordings in the drive pool and have no issues.

Then again, I have a quad core 9450 with 4GB RAM.
