Thanks for your reply, Lasse.
I've managed to get everything up and running (sort of) and I'm using the latest .cvs from the update in the first post, but when I try to use your MpXlobby skin I get a message saying it's outdated and it doesn't function correctly when loaded (buttons don't show up right, though perhaps this is because I'm running it widescreen?). M_ski reports the same thing on page 3 of this thread. Using any other skin works fine, so I suppose I will try to learn the new MP skin editor to make a TV screen that looks like my skin.
Anyway, my real question is how do I update your TV-only special build so that it includes the latest improvesments in MP? Apparently, changes have been made to the USB-UIRT section in the lastest CVS (since your 10/18 edit) and I'd like to upgrade but don't want to mess up any Xlobby>MP functionality you have designed. And once I do create a new MP skin, can I simply copy and paste the code for the button you've created that goes back to Xlobby?
Also, I can't seem to find any MP documentation or option within the Config.exe for selecting where your recordings are saved...
Thanks for your help. Not all of us are programmers or all that smart
