Send the report to dvblast mailing list. Possible problems that you are seeing:

• debug: Frontend "TurboSight TBS 6704(Quad ATSC/QAMB)" supports - This DVB card does not have drivers in upstream Linux, this means that the drivers are dodgy
• The fact that you are not getting anything quite possbily menas that the tunning parameters are not correct and you should check them.
