So I'm a little confused on this topic.. I've been wanting to build an HTPC thinking it was, essentially, a beefed up system that combines that functionality of a media player, cable box, DVR, and whatever else all into one device. However, the closer I'm looking, I think I've been mistaken on one point.
Originally, I thought you could use a digital TV Tuner to get rid of the need of a cable box. I'm using Time Warner Digital Cable with DVR, and I absolutely hate the cable box. It's some Scientific Atlantic something or other. Don't have the model with me at the moment.. but it is really slow in channel browsing, waking up from sleeping, and sometimes doesn't even wake up "good". Sometimes I'll wake it up and I won't get any sound. Or the resolution will be all whack and have a tiny window in the upper right corner. It stays that way until I change channels. It's annoying.
Anyway, back to the topic, I was hoping to use an HTPC as a substitute for the cable box. Is this feasible? Is it even possible?
Thanks in advance.
EDIT: I believe the current cable box is a scientific atlanta explorer 8300hd
