I'm running 8.10 beta2 and installed it via DVD. Pressing 3 and then selecting VGA2 worked just fine but was inconsistent with the web page. I opened the Nvidia X Server Settings tool and it shows that Nvidia driver is installed and functioning fine.
I'm using the following video card which is a newer than recommended but seems to be working fine. The OpenGL with alpha blending GUI looks great! I'm waiting for some cables to arrive so I can attach my TV to the system. I'm keeping my fingers crossed that it will go smoothly.

Having only tried using LinuxMCE for the last 2 weeks, beta2 was a huge improvement over the first beta. I never actually got the first beta to do anything useful since video was a mess and there was no audio. I have installed beta 2 a couple of times now from scratch just to make sure I was getting things set up correctly. MythTV is not being set up correctly. I spent a couple of hours this morning and I was finally able to get it working but I was hoping it just would work without any command line effort. It appears that kdesu doesn't exist. I made a link to kdesudo for it and ran mythtv-setup to get things setup. I'll probably reinstall from scratch and add the link before kicking off the linuxMCE install and see if everything just works.
