Don't know if anyone else has had this problem, but my M10 is pretty much toast. The delete button is stuck and none of the other buttons will function. I noticed it last sunday after a show, when i hit stop after the show ended, it immediately asked me if i wanted to delete the file. I got home, transferred the show, deleted it off the card.
Last night, recorded another show. It came out fine, but the problem is now worse. If i push the menu button, it immediatley goes to delete file, but i can't actually do it since none of the other buttons work. Tried prying up the delete button a little, but that did not change anything. Guess i'll be getting another one. I taped about 50 shows with it over the past 18 months.
