4 Tuner Tablo, Version 2.2.18, 2 TB Hard Drive 1.5 TB Free.
Problem - In fast forwarding through shows we will sometimes encounter grey boxes where thumbnails should be. It is not specific to any particular show and though it doesn’t always happen it seems to be in increasing frequency as of late. I have rebooted the Tablo to no avail. Mind you there will be a stretch of no thumbnails then they will start again. The number of grey boxes is somewhat random in length at least 3 but no more than 6 in a stretch. I would say this is fairly recent (like since the last one or two upgrades?) We hardly ever have 3 tuners running never all four. If you start playing in a grey box it plays fine, if you back up to a previous grey box it plays through the grey boxes without any problem. Also we are usually watching the show that was DVRed the next evening so plenty of time to generate the thumbnails. Any ideas? Thanks - Greg
