Hi! I'm looking to replace my remote on my Sanyo DS27890 CRT TV with a remote that will also control a Dish Network TR-40 CRA Digital to Analog Converter and an Emerson EWD7002 DVD player. I also would like it to be compatible with an RCA DTA800B1 Digital to Analog Converter (if possible) and (now I'm REALLY asking a lot) if it could control my WII that would be fantastic!
Anybody have any suggestions?
I may switch out the DTA boxes, depending on which one I like better. That's why I'm asking for one remote that would work for either DTA box. I've been using the remote that came with the box, the WII controller, and the old remote from my Dish Satellite Receiver. I just canceled Satellite service (And saved $80/month) and will have to return the remote with the Satellite receiver. Unfortunately I don't know where the original remote for the TV is located.

Get the RCA RCRP05B.

Sanyo: use any of TV 0154, TV 0847, or TV 1142
Dish Network:  Cable 2470
Emerson:  Video (DVD or DVR) 0675
RCA  Cable 2325

The Wii uses Bluetooth.  

Thanks for the recommendation! I just bought one on eBay....I'll report back to let you know the results.
Is there anything other than the WII controller that will control the WII? I'm not really familiar with Bluetooth controls...
If you can point me in the right direction for a tutorial on how Bluetooth controllers work, I'd certainly appreciate it :-)

Got my RCA RCRP05B today from eBay for $10.16 from remotexperts. Used condition but looks practically new (Shipping took a little longer than expected, but shipping was free). Didn't ship with instructions, but they were easily found on the 'net. Set it up to work for the first 3 devices in under 10 minutes. It also has a few nice features such as the ability to turn on the DTA box first, then the TV with one press of the power button (as opposed to forgetting to turn on the DTA before the TV and getting a loud static noise). Another nice feature is that the channel up/down is "locked" to the DTA box by default (and can be changed). This prevents the TV from changing from channel 3/4 (whichever your TV is set to) when changing channels-pressing the channel up/down changes the channel on the DTA without first pressing Cable/Sat.
 The remote has MANY controls (not all of which I have figured out yet-but I've only had it 30 minutes :-) ), and has the ability to "learn" from other remotes. It
feels nice in my hand,and is a pretty good deal all around. It uses 2 AA batteries.
 Thank you for the great recommendation!
