I can. The issue is the strange frequency. Most microcontrollers and processors are made today to use a evenly divisible clock frequency. I want to use the Propeller because it have built in video generation, but it works best with a 80 MHz clock (delivered via an external 5 MHz source clock and its internal PLL). Since there is an unique pixel on the video line at each clock pulse, I cannot simply read the video signal and act upon it. 0100011100000 would look like this to the Prop: 01010. Clearly not the correct pixel data. This means that I must run the prop at the 15.6672 frequency and test the video pin at each clock pulse. However, looking over the Prop's data sheet is not giving me much hope that this will work.

One thought I had was to use a serial in/parallel out shift register running off of the 15 MHz clock. Then all I would need to is read each output of the shift register with the Prop. This would guarantee the correct pixel data. At least I think it would...
