The cord for the ir sensor that goes with my Hauppauge PVR-250 is too short. When I try to use the remote, half the time nothing happens because the signal can't reach the sensor. So I went to Radio Shack to get an extension cord so I could reposition the sensor to a more favorable location. I'm sure I could have found the hardware myself just fine, but this store employee came over and insisted on helping me. I told him what I needed, an extension cord for a 2.5 mm stereo mini-plug. He informed me they didn't have extension cords of that size, only cords with the 3.5 mm jacks. "Fine, give me two adapters for each end on one of those. I already have one at home." He went through the rack and handed me one for one end. I checked it out and it was the correct adapter. He came up with another one and for some reason I trusted him to have the right one. Doh! I guess I was just a little anxious to get home. Anyway, I get home and pull out the adapter and it's a stereo to MONO adapter! Totally useless to me. The funny thing is, I must have mentioned to him about five times that it was a stereo plug that I was using. Stereo, stereo, stereo! I wish people weren't so goddamn helpful.
