I have been considering this for some time now. I have Comcast cable which as many of you know sucks but that's not why I want to eliminate it. I use the newsgroups to download my TV episodes so I haven't really been using my SageTV DVR as I have been streaming my videos from my PC.
The quality is better than my DVR can record. Even if I had HDTV and HD cable, it's not as good. Also, living on the West Coast, I sometimes even get my episodes before it airs in California.
My only issue is being able to channel surf. I watch a lot of TV and streaming newer movies and watching entire seasons of downloaded TV shows can meet it's end relatively quickly. I suppose I could use my library of movies when I want to just veg out in front of the tube.
My problem lies with my bedroom TV. I can't run an ethernet cable there so giving it access to my media needs to be wireless. If anyone has a recommendation for something good here, I'd appreciate it. It doesn't need to store anything, just receive streamed media over the network.
Have any of you cut the cable yet? What have your experiences been?
