It sounds like that is where your cpu usage problem is. I think the front-end will be trying to resize the output when it doesn't need resizing (because it's already at 720x576). But what you've changed doesn't modify the resolution of your X output. What I think you want to do is create an appropriate mode line in your /etc/X11/XF86Config-4 file to output X at 720x576.Yes, I believe that is the correct resolution for PAL. Where exactly are you setting this resolution - as you state below, X doesn't like resolutions that aren't available on your video card.
In the mythtv ASettings -->T Vsettings --> Recording Profiles --> Software
Encoders on the Image Size screen.
Thanks Craig. Just so I'm clear, then, are you advising that I leave the settings in the Image Size setup screen as 480 x 480 (which I think is the installation default)?
Under Utilities/Setup->Setup->Appearance->Screen Settings, I have zero in all of the settings (GUI width, height, X offset and Y offset) and "Use GUI size for TV playback" is checked. MythTV should then use whatever the resolution of X is (ie. 800x600) and my NVidia TV out then rescales to the 800x600 signal to 720x576 when it outputs as PAL (sort of the reverse of what Steve Cristall is getting).
If you set it up this way and change your X settings to output at 720x576, there shouldn't be any rescaling at all from the input signal to the output signal. I did try that, but (like Steve) I didn't get it working 100% and stuck with 800x600 (which works fine).
Some people have also said that they get a better picture when receiving a HDTV signal, even though it's being displayed in a standard def set. So changing your X settings to 720x576 might or might not improve your picture quality.
I don't think I've been using any of the recording profiles at all (all my profiles are still set at 480x480) and all of my video is still in 720x576 when I watch it on another machine. When I look under the recording profiles, I have "Hardware DVB Encoders" (I don't have a hardware encoder) and "Transcoders" as the only two entries (and I don't transcode anything). I'm using a Twinhan VisionPlusTER (no hardware decoder) and I leave the video in the form it was recorded in until I burn it to DVD and/or delete it.
I think the recording profile you're using is most likely the source of your high CPU usage.
