Search for Fiire here in the forums, I'm sure you'll find what I'm talking about..
...for those who need to be spoon fed...
MythTV does NOT work on Fiire Stations. It's a limitation of the ViaChrome Pro II Driver. (only available through fiire)
UI/2, while is DOES work, it doesn't have menu transparency like the NVidia drivers do.
I have both a 1" AND a 2.2" Fiire Stations, along with 2 Fiire Chiefs, Fiire Engine, etc, etc, etc,
Take my advice, do *NOT* get *ANYTHING* with VIA chipsets. I have *also* tried running UI/1 with MythTV, and also, a NO GO.
Now, There is a nice MSI Medialive... That's what I'd go with, armed with this very omited, but important information...
Oh, and just to let you know... I was the first person here to report on Fiire Products. You'll find a comprehensive thread on the Fiire Station if you search for it.
