Hi. Love my Tivo's....all 3 of them! Have an occasional problem from one though. The ATTivo. Had it a few months and every so often (probably around once a day for a total of an hour?), the audio becomes very tinny. A little high pitched squeal....not quite static, but sort of like the high pierced sound you might get at the edge of an AM radio signal? Don't know if this makes any sense, but..... It only happens here and there. It might start up 20 mins into one show and run the rest of the show, but not happen again. Might start and then stop 20 mins later. Sometimes it's there, sometimes not. It's not the cable. Like I said, I have 3 Tivos and it ONLY happens on recorded shows on the ATTivo and with live TV on that Tivo. It's an audio problem I have narrowed down to ONLY happening with that one. It's not so annoying that things are unwatchable, but it is annoying and makes it tough to work the sound. Loud enough so I can hear the dialogue, but not so loud as to get too much of the squeal. Fortunately, it really doesn't happen much. Like I said....an hour, probably less total time during the day. Still, wondering if anybody else has ever had a problem like this or if there's a fix....besides sending it in?
