Thanks everyone for all the useful information on what is happening with the OTA channels.

I am not sure if anyone else has had this issue but as of Sunday July 15, CFTO Channel 9, from Toronto has had excessive macro blocking,and drop outs and today has totally failed on me. One TV just says retrieving information, and the other shows no signal strength at all.

I live in Burlington, Ontario so correct me if I am wrong as I should be able to get it with just and indoor antenna direct to either of my tvs, which I have tried, yet nothing.

As I thought it might be an issue with my existing setup, of CM4221 (Toronto), CM4228 (Buffalo) combined and sent through a CM777 amp.

Any thoughts or help is appreciated.
