I've also been having problems with CityTV HD, and also for the last couple of days. Prior to this, I've always received it with no problems here in mid-town TO.

My TV indicates a solid signal, but there's no picture or sound at any time. I'm also obviously not getting any PSIP data, since after re-scanning all the channels, it stays mapped to 53.1.

All other channels remain fine.

Any thoughts?
