Last few weeks been noticing an increasing amount of what I'll call "tuning" problems with my XL4/Elite. I spent some time testing this afternoon and it really is quite a mess. In a nutshell, the TiVo seems to be unable to tune a channel at times and leaves me with a black screen the scrub bar showing 30 minutes and "paused." Unlike the typical problems i've had in the past with my TWC tuning adapter, there is no "unable to tune" error message or authorization message.
Here is an example:
Was watching CBS, hit guide and tuned to HGTV, hit "last" and then CBS wouldn't tune (black screen scrub bar at 30 minutes paused.) Hit channel up/down and CBS would not re-tune. Hit guide, then selected CBS and it tuned. Was able to replicate this type of behavior with 3 other channels, some taking more effort than others to get back. If i toggle the "Live TV" button to switch tuners while on a "blacked out" channel the other 3 seem to be fine.
That's just one example, but I'm noticing a channel work perfectly fine and then stop working in a similar manner all too often in the last few weeks. Have missed recordings as a result, and while I'm normally the first to blame the tuning adapter it's happening with channels that I don't believe are even switched (and the behavior is different than problems I've seen previously with my adapter or cable card.)
Unplugging the box and re-plugging also will bring a channel back online. There isn't much rhyme or reason to what channels stop working. But it is happening, a lot.
Any thoughts would be appreciated. Thanks
