If you haven't done so yet, Sam, you should subscribe to Jason's HTPC/JVC thread. Hopefully, we're going to hammer out the solutions we all need to get our HTPCs and media servers working properly with the JVCs. There's already progress, but we have a ways to go. Unfortunately, that's almost always the case with computers.
I still think it would be a good idea to summarize the progress of that thread at the start of this thread, too. You have the slots reserved, and a one-stop solution is always attractive to owners, IMO.
If anyone can PM me the current summary or status as it stands, I will post it in one of the first reserved posts.
