I need some advice. I currently have Directv, using a HR21-100 receiver (which I own). I am wanting to drop service and go directly with using Netflix, Hulu Plus, and my local OTA HD channels. One problem, my 6yr old 42 Vizio's HD Tuner went bad, so I can't pickup my local HD channels anymore with it. So I am looking at other options. Here they are: 1. Use my current HR21-100 receiver - use the AM21 tuner with it to get my channels - not sure if this will work w/o service. 2. Pick up a Dishnetwork 811 receiver or Directv's HR10-250 to pick up OTA channels - not sure if this will work either w/o having service with either of them. 3. Use a Digital to analog converter - I don't think I want to go that route since it may down convert the signal to SD resolution Are there other inexpensive options to get my local OTA HD channels? I don't really want to spend too much on fixing this issue since this spring I am wanting to get the Simple TV, which has it's own built in tuner. Any suggestions?
