I think you're right on the DTA1080U for u-remote. I originally thought it was DTA1080D-U. That's a good price on that Amazon>Tiger link.
My Mom has an RCA that looks like that but not sure of the model number. I can't attest to its performance in detail because she has it connected to a tiny TV using a very cheap UHF antenna in her sunroom, but it seemed to tune in well and look OK given the setup. I do recall that the remote is very basic for the TV side, like only controlling TV power and audio; it also had a cheap look to it.
Here's another website you may want to look at if you're not familiar with it:http://www.consumerreports.org/cro/e...d-notes.htm#30
Don't take everything there as gospel as some folks here say there were some problems with their analyses, but it's a good general overview. The forums here are better once you're ready to 'zoom in' on specific models.
Try looking at the audio menu in that Access box. My Zinwells have a feature selection for RF and Line Modes; RF is louder and I suspect mono while I suspect Line is stereo (they fail to explain why other than to use RF for coax and Line for composite although both modes output sound through both connections in either mode setting).
I personally like using a fancier (vs basic) u-remote because they have so many functions I can control like menu, guide (EPG), VCR, DVD, etc. There's still a few unique functions I infrequently have to grab the device remotes for like TV PIP, converter aspect ratio, etc. (maybe the high-end u-remotes have these functions?). And like Ramm stated you can control the TV volume independent of the converter; my Philips has a punch-through feature where I can set certain functions of one mode to work in other modes like that. I suspect most of today's u-remotes will control converters. You can tell them to open the package so you can read the code list (some have a list on the package but say '...and many more - see code list inside') or return it if it doesn't work
. Maybe you should buy just one and give it a try first.
BTW, do you do any timer recording? If so you might return a few of those Access boxes and buy some Zinwells. I use a ChannelMaster for my main TV (s-video picture quality) and Zinwells for my VCRs and other rooms (although I just added an Artec to my bedroom TV/VCR setup because it has a nice EPG).
