TimV, to check current version: Remove discs, hit "setup" on the remote, go to "general", then scroll down to "Maintenance", click on "update", it should show current version like v1.2/T17, or v1.3/T19. Hope this helps!
Mikeb33, I would think if your wireless device connected to the Tivo gets you a wifi signal, then it should work if you plug it into the HD-A2, I have to re-add my HD-A2 to my network each time I drag it out into the family room, and plug in the RJ-45 cable from the router. I hate dealing with moving the HD-A2 and plugging stuff into my router, so that wifi wireless link sounds like a great idea, but BB never has gaming wifi adapters in stock in my town.
I have found that once it is added, setting DCHP (or DHCP) and DNS to "On" makes the whole process of avoiding the "Can not find out server" much easier.
Enjoy, but I don't think v1.3 did much of anything for me, except not allow me to play "Children of Men" HD DVD side AT ALL! Thanks Toshiba!
