I know this may sound a little nutty to you guys, but where can you find an RF modulator that outputs a digital cable signal? See at my house during planned events, I sometimes make my own TV channel that broadcasts my 2nd desktop throughout the house (my brother brought me 2 DRAKE analog channel masters that lets me turn channel 3 into 80 or some other channel). I know the cable signal cant get out of the house due to our one-way amplifier so that's no issue in case your wondering. But since were starting to receive digital transmissions (OTA only), I was wondering if it was possible to obtain a device that can turn a S-video or component video signal (with audio) into digital cable. This is for specific purposes though cuz when I want to show a movie streamed from the internet onto my big screen tv, I don't want to haul my pc out to the living room. I just want to stream it onto a second moniter that outputs to a modulator so I can view it on my tv 2 rooms away.

Ive read some stuff about some dude who ripped apart a vga cable and jimmy rigged it to output a digital signal to his tv. It also included messing around with video card drivers, which ive had bad experiences doing.
