I'm so excited- I just ordered my first iMac (20" Intel version) this morning (this is also my first Mac computer of any kind)! I'm using it primarily for video editing, but I'd also like to be able to watch TV on it. It's going to take the place of a cruddy 13" TV in a rec room. The TV is currently hooked up to my ReplayTV, which in turn is hooked to my DirecTV satellite receiver. Would someone mind recommending a good video input device for the iMac?Since I already have a ReplayTV (actually a pair of them), I don't really need DVR capability. The RTV also functions as my tuner, so I don't even need the device to have tuner capability. I also don't need video capture, as I use a MiniDV camcorder which also functions as an analog/digital bridge if I want to capture from analog sources (I just don't want to use the camcorder as a bridge *all* the time just for watching TV). I guess I just need something to convert the signal to USB. Any ideas?
