I broke my "peanut" remote that came with the THR22-100 (DirecTV DVR w/ Tivo). I have been content to go back to using one of the old "universal remotes" that I had laying around from my non-Tivo DVR. But... is there a way to "thumbs up" or "thumbs down" using the universal (non-Tivo) remote? I heard there was a way of using a combination of key presses to affect the same result as a "thumbs up" or "thumbs down", without the benefit of having the actual keys on the non-Tivo remote. Any help is appreciated - Thanks!
