Hello! I'm looking into buying my husband the EyeTV HD to use on our iMac. We currently have a regular TV in our bedroom, and our iMac...ideally I'd like to be able to use the iMac as our TV (even if it's only watching DVR'd content). Right now we have one cable box in our living room, and I know I'd be able to feed the cable connecting the EyeTV to the cable box thru the wall. Here's my question - will using the EyeTV mess with the DVR we have thru our cable box? I want to be able to watch content on both, or have our DVR recording something, and the EyeTV recording something else. Is it an either/or type scenario?
