Ehm, you want to use the arial out of the A1200 to connect to a TV card? Maybe it would be a better idea using the composite out and connecting it to line in on the TV card. (oops that's what you mentioned later). Do not search for channel 36 when using this but you need AV1 (or something similar)
Would't a Scandoubler/Flicker Fixer be a better option?
