I found the aswer to my question above. The card was in DVB-S mode. Using the TBS6522 mode change tool, I was able to switch it into DVB-T mode and all is not working ok. Problem solved.
I am using CrazyScan2 - Version 1.0.2.158 with TBS6522 Card. I am getting message "RFScan2 not supported!" and hte AirScan button is greyed out, I have uszipped CrazyScan2 (1.0.2.158) and StreamReaderExEx-BDA( StreamReader.dll version 1,2.4.52) into the same folder. Please help. Thank you.
