Hmm if there is no copy protection on cable, whats stopping people from recording premium channels? Unless I completely missed something, which is very well possible, at this time you cannot use HTPC to record premium channels (HBO, MAX, etc).
The reason I thought about using the above mentioned device is not to backup my DVDs, which I can already do with AnyDVD. I thought that it might be able to strip copy protection from the TV signal so one would be able to record premium channels.
