This problem just started happening. When I try to tune into one particular channel, it takes 15-20 seconds every time until the picture comes up. This only happens on the Verizon FIOS version of the channel coming through my HDHomerun Primes. My antenna source works fine. This has been happening for a few days. It does not happen with the HDHomeRun software nor any other channel so far.
It also does not happen with the non-beta version of Channels so it looks like some difference with the beta. I'm running the latest beta.
I just submitted diagnostics around 12:22pm. It's channel 504 (WTAE).
