How much CPU do you need for dual tuner? (1 Viewer)

[CodeMonkey]

I have a system with the following specs running MP RC3 with a PVR500MCE dual tuner card:

P4 2.8gHz, 512MB memory, nVidia FX5200, 40GB HD, 200GB HD

I have it configured fine, and it uses both tuners. However when I watch on one tuner while recording on another both the recording and live TV gets choppy and the audio gets way out of sync. Doing either alone works fine, its just a problem doing both at the same time. Does anyone record and watch TV at the same time without problems? What are your system specs? I would have thought a P4 2.8 gHz would be enough, but apparently it is not in my case.

FYI: I have the watch tuner set at priority 10 and the recorder at priority 9. I also have one set for watch only and the other for record only.

Thanks in advance.

Humm, that seem skin of strange... if you look at my sig I have a machine that is pretty close to yours. I don't seem to be having that problem. I would check to see how much CPU it takes when both are recording but no video is playing on the screen. Mine is usually around 10 to 15 % which is not much at all. I would also try different codecs to see if that makes a difference. I am using Nvidia pure video.

I had a problem with dual tuners at first. Couldn't use both cards at once with similar results to yours - although it was only one card that got choppy.
Turned out to be driver related. An update to the newest drivers and it was fine.

Thanks guys. I am also using nVidia pure video. I will check the video card drivers, but I had just updated the capture card drivers. Also, I had the record quality set on high. I will try setting to medium.

Thanks again.

As said that should be plenty of grunt because my Sempron 2600+ can handle 2xdvb-t and a pvr-150 at the sametime. A P4 shouldnt have too much of a problem.
