Converting RF to HDMI with a device is no different than allowing the HDTV do it itself. Both will look horrible.
Here's my dillema: If I plug my CV into my LCD via RF, I have to switch the source to the TV Ch. 3 input and I don't get audio to my receiver and I have to turn up the TV volume which is annoying. My Yamaha receiver does not have an RF input so my only options are to go RCA composite, RGB or HDMI. I can get a DIY composite mod off ebay for $23 which looks fairly easy to do soldering 4 wires to the PCB but why even go that route when RGB is better but Yurkie has said he is not offering DIY RGB kits and his mod is only for use with the prohibitively expensive Framemeister or his $40 HD converter which essentially does the same thing that the $28 digital converter from Walmart does but the best I'll be able to get from that will be to go with the RCA component video DIY mod.
Basically, I'd just be using the digital converter as a cheap RF demodulator to pass the signal through to my receiver input so I can get sound through my external receiver speakers anyway and not the TV. Right now I have it going RF to my LCD and the TV scales the video just fine, it just looks a bit fuzzy as expected from an analog RF signal and I would expect the video to look about the same through the digital converter without doing any other mods. I have seen a couple of RGB modded systems on ebay but I remember one of them had a problem with the chroma looking too bluish so that was an easy pass for me. All I am interested in is getting an RGB mod for my Coleco and not the controller mods, pause button, LED power switch or any other mods.
