It's getting there. I did not get the error in the config but how I get a error when trying to access live TV. Here are all my config files I hope this will help.
It looks like you have two recording sources set-up. You'll need to re-setup both with version 8. It does look like it was half working (config.exe-l.log) and then something went pear shaped :-(
Try re-configuring your capture devices, hopefully that'll work :-)
can you send me a screenshot of your 'nVidia WDM Video Capture (universal)' device from GraphEdit. I'm making an assumption that it will have 'Preview' and 'Capture' output pins and I'm assuming that this is perhaps not the case.
