If you've got a ATSC tuner - try it out. the OTA HD on CTV/Global in Calgary, look in my opinion, much better than the compressed service Telus/Shaw/Bell offer.. Sean >> which makes no sense. Your only option for HD with these cards is >> ATSC, or off the air HDTV signal: here in Calgary CTV on UHF 36 and >> Global on UHF 41 (I think).
