WORKAROUND: I just discovered that setting a "record" instruction for the channel with a dead buffer will reset the non-functional buffer. Upon noticing a channel lacked its green time-bar (i.e., a dead buffer), I pressed the Guide button, then clicked on the very next scheduled program for that dead channel (should be within the next half-hour). As soon as the scheduled recording began, the dead buffer was reactivated. Yes, the red reset button DOES reactivate a dead buffer, but that workaround disables both tuners for 5 minutes or more, while also losing some settings and user prefs or pointers in the DVR. I evolved the above workaround for a dead buffer this morning, when trying to avoid a full reset. BACKGROUND: In my experience, pausing a dead buffer freezes the green-bar progress timer (at say 26 mins). If I try to record the channel with a dead buffer, I just get a blank recording (black screen) that's also frozen at that same timer point. Changing by one channel (up or down) DOES activate a new buffer for that new channel. But I find upon retuning to the original channel that it still has a non-functioning, dead buffer. Today, scheduling RECORD for the next program break re-started the buffer. Hoping others finding a dead buffer might please check out the workaround & report back.
