Unfortunately, I just did the upgrade to 22.14 and now my 2 channel Tablo no longer will show live shows. I hate it when companies put out software that hasn't been tested.
My Tablo has been working for about the last 6 months without a hard drive. It never did recognize any external hard drive I tried although it would recognize a thumbdrive. The thumbdrive didn't work very well though as it caused the live tv to stutter but since it worked just fine without a hard drive, I was ok with that.
Now it will give me an error message that it can't play the tv. I don't even know how to back out of the bad version and go back to the old version. If it isn't fixed soon I guess I'll have to update my review on Amazon.
