Please look in http://www.network54.com/Forum/27766/message/1134164002/DCR-TRV725E+C-31-42+error+-+the+solution- I'm copying what I've wrote there: I had the same C:31:42 error on my DCR-TRV725E. Suddenly, out of nowhere, it started. On every cassette, sometimes with few seconds disturbed playback or few seconds of rewind/forward. I searched the Internet and found this forum. People here said that the solution was to take the camera apart and put it back together - well, it WORKED !!! I took out all the screws I could see (except the ones near the LCD). Note the two different screws near the button panel opposite the LCD screen. I pulled out the front of the camera, and then separated it into two parts in the middle all the way from the lens to the battery. In the cassette compartment "area" I only took out the plastic cover (didn't touch the screws of the mechanism inside). Be careful on the cables connecting all those parts. The camera was disconnected into 4 parts (lens, left with LCD, right with cassette compartment and battery, the 4th is this small i.Link cover on top aside). The ONLY thing I touched was this small transparent purple stick near the middle of the cassette compartment - just near the drum. I cleaned it a bit with ear cleaner. I don't know if this did the trick, but that was the only thing I can think of. Then, when the camera was all wide open, I connected the battery, inserted a cassette - and it worked. I felt like in terminator 2 when the robot comes back alive. I saw that the tape is rolling and not stopping and beeping, I could not look through the eyepiece since I had to hold all the parts in my hand, so my girlfriend looked. I put all the pieces together and it still worked. I could record and playback. All this disassembling and assembling happened 2 hours ago. God bless the Internet :)
