Sounds very similar to the same thing I posted about yesterday on several of the Fox Sports Nets.
Mine were stuttering in a repeat loop of the same split second of the video. On all the Fox Sports Nets I went too.
Then a few minutes later was back to normal.
A reboot did not solve it.
So this was ATT/DTV screwing up and then fixing.
Something weird is going on at ATT/DTV if they've done this two days in a row.
Is this the new DTV norm.
Like all the other issues the past year or two.
The gold standard in fast becoming the lead standard.
