Maximum/native/recommended S-Video TVOut resolutions for IGP9100 radeon?

[Mark Knecht]

Hi,
   I'm wondering how I determine what resolutions are supported using
xf86-driver-ati with TVOut turned on? My machine is an older Asus
Pundit-R with an ATI IGP9100 chipset. I have the Open Source driver
running and it's currently set to 800x600 (recommended on the Xorg
site) and I'm getting a pretty good picture compared to the older
closed-source ATI driver. Big improvement on the noise though. The old
ATI driver used a lot of CPU and made the fans run at high speed. So
far your Open Source driver doesn't seem to kick the fans up at all so
thanks for that.

   I've read on the web that S-video was inherently limited to
720x480. Is that true? Does the IGP9100 support that sort of
resolution? This machine is hooked only to a TV and only used for
MythTV so there are no other considerations other than getting a good
picture a few hours a day.

Thanks,
Mark
