I'm using ATI 9100IGP Radeon on-board video with no problems. Have you tried your card using the official drivers and also tried the GATOS OSS drivers? The cut-off for support of ATI cards in the official drivers is the Radeon 8500, so you should be OK. It's therefore likely you need to do some more tweaking (are you using S-Video to connect to the TV?). > I want to replace one of those components, by my question is whether it > makes more sense to get PVR-350 (I don't need dual tuners of 500, since I > use cable box) or nice NVIDIA graphics card for better support for linux? If you find you have a supported ATI card, I'd keep that, unless you're using some very low powered machine. I first got my PVR-350 and started using its beautiful TV out before ATI had fixed their drivers to get TV-out running on my Radeon 9100s. Once that support had stabilised, I've been using the ATI for TV-out via S-Video and have not looked back yet. The accelerated X driver for the 350 has come on in leaps and bounds, but still doesn't offer the range of tweaking that the regular ATI driver does, nor OpenGL support (the 9100 doesn't have 3D support unfortunately) In terms of watching standard def TV, the PVR-350 wins hands down against my ATI card (the difference is noticeable). However, for the extra functionality the ATI card provides in terms of MythVideo etc, and future HDTV support, I'd recommend exhausting this option first. I'm still happy to have my PVR-350 though, aside from a great encoder, the TV-Out is brilliant when required.
