A current, there is no solution for PCI based TV tuner cards for OS X.
With that said, there are other solutions using other methods.
ATI has a USB edition of their TV tuner that is supposed to work with OS X.
Formac at current still have not decided to bring support to their customers that have the Formac ProTV Stereo PCI cards and basically to us that if we really want TV on OS X, we need to spend an additional $499 (last I checked) to buy their ProTV Studio, which all-in-all looks like a good product but is just too expensive to just watch TV (Plus it's Firewire).
According to BTV, in order to use their software you still need valid video drivers for the hardware, BTW is not a substitute for missing OS X drivers.
I really think Formac needs to stop being cheap and support the new operating system fully and provide OS X support for their ProTV Stereo TV Tuners. I pulled mine out and vowed to never use it again unless they add this support.
I'm sorry your right.. I never bothered to check out their site regarding drivers. I just remember talking with a rep while at MacWorld Expo and that was their recommendation. I ignored it mainly because I don't like video via USB, but I did ask for TV solutions on OS X and that is what he suggested.
I double checked and I did not see anything on their site, so I guess there is a lesson to learn here, don't trust ATI reps.
I can tell you this though, who ever comes up with OS X support first (Nvidia or ATI) by providing TV tuner support either built in to an All-in-wonder unit like ATI's or on a seperate card will get my business.
Next time I'll check my sources more thoroughly before posting them.
I checked out BTV's website and found this info about current tv tuners out on the market and that none of them have OS X support. Then I saw one on the list that I thought did have OS X support. Check out MyTV. I bought one with my Tower G4, but later on sold it because I don't like video over usb (I had to try it to learn that I hate it).
But they do mention the ProTV from Formac and that it may capture video from the card, but it would not be able to change the channel.
I guess we are stuck here waiting for someone to do something about this. .. no worries though, got my PeeCee right next to me that has the ATI TV Wonder PCI so that I can watch tv while I play on my mac.
