PVR-150/SageTV CPU usage?

[jcuecker]

I recently installed a PVR-150 and am getting a CPU usage value of around %70-90. Does this seem right? I though the PVR had hardware encoding.

CPU: AMD 3500+
GPU: Geforce 6600
RAM: 1GB

You've got a problem. With that setup, I wouldn't expect your usage above 30% (even that might be a high number).

Yes, it has a hardware encoder for recording, but your video card & cpu are used for playback. List what you are
using as the video decoder & renderer.

Note that if you are using VMR as the renderer & you are putting playback on a 2nd monitor, 3D is emulated on a secondary monitor, so whichever monitor is used for playback needs to be set as the primary monitor.

Thanks for the sugestions guys. Here are my decoders:

Default: 9-10%
Nvidia Video Decoder: 10-15%
Nvidia video Post Processor: 35-40%
SageTV MPEG video Decoder: 25%
ffdshow MPEG-4 Video Decoder: 80+%

I played around with them the percentages are their respective CPU usages in my system.
Mine was set to use ffdshow. I did apply some rather agressive settings to ffdshow for use with TheaterTek.

So what decoder should I use? ffdshow does look the best but it sometimes taps out the CPU and causes stuttering, so thats a no go. The differences between the other decoders wasnt as aperant to me. What decoder does default use? what decoder should provide the best reults (sans ffdshow)?

Nvidia Purevideo is your best bet. I always recommend that for Mpeg2 recordings.
