Update - the TBS card was NOT the cause of the problem. The sensitivity of the TBS 6981 seems fine. Has anybody compared the sensitivity of the TBS 6981 against other cards? I have missed a ton of Olympics recordings because they either didn't start (no lock) or were unwatchable due to high errors. [-]I thought my dish was perhaps out of alignment but the next time the TBS 6981 was struggling (wouldn't even lock) I tried my Hauppauge HVR-4400 and it picked up the same transponder perfectly (no errors, let alone locking first time)[/-]. I really wish Hauppauge would get their back sides into gear and release a dual tuner version of the 4400. I hadn't noticed this until the Olympics, where the weaker transponders were brought into use temporarily. Also, both tuners on the card behave equally.
