I just picked up my DTB-H260F at my local BB in Northern VA. I went there yesterday and their computer registered two in inventory, but they couldn't find one in the warehouse. The units were officially scheduled to go out on the floor today. When I got there today I spoke with the same salesperson, and apparently they really had only one unit. The other was a fake display model.
Like many others I got it to improve the quality of my analog OTA picture. I don't have an HDTV, and I stopped getting cable TV because they just raised my rate to 50/month for basic cable, of which we watched only two channels that were not provided OTA.
About the unit. I can confirm that the On-Screen-Display does not work with the composite out, even using the 480i output setting. Pretty dumb choice if you ask me. Lucky for me I have a single TV with the Component input and that worked fine. You can't really use the unit without the OSD - you have no clue as to the channel you are watching and there is no way to setup the unit.
Also the unit does not scale some content to the 4:3 aspect ratio. The content that was already in 4:3 looked fine, but the other content would be this square box - with black bars on the left and right of the picture. It's certainly not very attractive. You can change the picture format to full, but then it drops some of the image on the top and bottom.
My next effort is to hook this thing up to my ReplayTV 5060. I tried it a little while ago, but ReplayTV unit does not understand OTA set top boxes. I called them and the don't support DTV even with set top boxes. Plus their suport group is extremely dumb and uneducated. (They kept saying the RTV does not support HDTV - I don't want HDTV, I want DTV via a set top box!) Ugh.
Man I love the picture (aside from the aspect ratio). Before the ATSC STB, I was I was getting multi-path ghosting even with my yagi directional antenna. Now it's just a crystal clear picture, and more channels to choose from (I get around 30 in our area - but not all are in use or english).
