Is anyone else experiencing ongoing pixalization/cut out issues on the Discovery channels (Discovery on channel 42 and Discovery Velocity on channel 534 -- the latter is now on free preview)? Seems to happen every few minutes (both live and when recorded), and makes them difficult to watch.
I just watched Daily Planet episodes from January 8/9 without issues (Channel 574, which is the same as 42). Do a reboot and check your signal, or call Rogers and have them check your signal. Most pixellation/cut out issues are related to a poor signal either in your home or in your neighbourhood.
Most definitely could effect only specific channels.
With channels, they are transmitted over the cable. To allow more across at the same time, different things are transmitted at different frequencies. A bunch at one frequency, another bunch on slightly higher, etc again and again.
The interference or signal drop may only be effecting a specific range of frequencies.. therefore effecting only specific channels.
Signal sounds OK. You may want to check at different times of the day and when the issue arises. Sometimes there are other issues outside signal that can cause these issues - like problems at your node, etc.
If it continues, you may need to call Rogers. If it happens all the time, it should be easy to fix. If it's intermittent, that can be more difficult.
