Shaw Direct carries only one feed APTN East, not sure if they carry the HD feed.(available through out the US)
BTV carries APTN East, APTN North(which only slightly diffrent then the East feed mainly Government News is different), I'm not sure but I believe they also carry the HD feed which has totally different programing then the SD feed. The only draw back with BTV is it doesn't cover all the US. I'm not exactly sure where your located in the US or where exactly the siganal cuts off(SD vs HD)91 vs 82 sats. Perhaps others could be wade in who live ion the US, I'm in Canada.
