I recently added a DTC100 receiver to my collection as a backup for my Mits SR-HD5. I connected it to my WS65087 for comparison sake, and I have a few observations. (1) The fan on the DTC100 can become a bit annoying (if you are thinking about it). (2) The Mits menu is way better than the RCA menu, but the RCA menu responds to remote commands much quicker. (3) The Mits APG includes both OTA, cable and sat stations making it easier to go from one source to another. On the RCA you must press input to go from 1 source to another. The OTA stations do not show any programming on the RCA while they do on the Mits. (4) OTA digital stations on the Mits map to their analog channel (ex: 4-1) while on the RCA they map to their actual UHF channel. (5)It's easier to check OTA signal strength on the Mits than on the RCA. (6) It's easier to change the screen aspect ratio of non-HD stations on the RCA. (7) Picture quality is about the same on each. (8)The Mits seems to have a more powerful OTA digital tuner as well as satellite tuner. That's about all I can think of now. Oh yes, the Mits costs about $300 more. I hope this helps any prospective HD-tuner purchasers.
