My quest to get my TiVo fully functional continues. The port forwarding I was looking for earlier seems to be emminently doable with my Mac. I found this firewall configuration software originally called Brickhouse but now called Flying Buttress. With it I should be able to get the appropriate ports forwarded to my TiVo.
I even found this TiVo Forums post detailing some ways to test my connection to it and this TiVo support page detailing the ports I need open.
I'll have to wait until I get home tonight before I can test some of these things out.
I'm also trying to get my PowerBook hooked back up to my TV so that I can use my Bluetooth keyboard (and pick up a BT mouse) for controlling the computer from my couch. That way I would be able to check baseball scores (or watch the MLB GameDay) on my TV and get streaming audio through my surround sound system. Plus, I would be able to play DivX movies on my TV that way.
Someday, when I get a new HDTV I'll try to get a Mac Mini and see if I can switch this system over to that. It should be able to handle all the things this PowerBook does, plus it would have the standard remote that all Macs come with (and Front Row) making everything much easier.
In the meantime, I guess I'll keep slumming it with my 500MHz PowerBook.
[UPDATE 12:02 PM EDT: Tonight is the premier of the new season of Always Sunny in Philadelphia on FX. The show is hilarious (now with Danny Devito!) so catch it if you can]
