One live broadcast channel, channel 13 on broadcast TV, sometimes works fine, but more often than not plays normally for 23 seconds before a progress bar comes on, followed by a repeat of the same 23 seconds of broadcast TV. This cycle repeats endlessly, always reverting to the same 23 seconds of TV until I switch to another channel. Invariably, the new channel plays perfectly. If I then return to the troublesome channel, I get a new 23 seconds of the current broadcast, followed by the same endless cycle of progress bar followed by the new 23 second broadcast clip. I've rebooted the ROKU device, but this has no effect. Firmware is up to date. All I can do to watch something on this channel when this is happening, is to watch 23 seconds, switch to another channel, then after about half a minute, switch back to the troublesome channel to see another 23 seconds, and so forth. This seems to affect just one of my broadcast channels, and, I should add, does not happen all the time. I have two ROKU devices, each hooked to a different TV. When I'm having the trouble, it is not working correctly on both ROKU devices, and always with the same broadcast channel. Has anyone seen this before? ROKU Systems says my wifi signal is excellent. I have tried switching ROKU to a different wifi network, but the same problem continues.
