Help determining why recording is failing?

For the most part, my recordings seem to go off without a hitch. I’m running PMS 1.9.3 on a Windows 7 PC using a Hauppauge WinTV quadHD card. But every now and then, a recording just “fails”–never starts and never gives a good indication of what went wrong. I’ve checked logs and can’t really tell if it’s a signal issue or what (I don’t often have times when I get a bad signal). This happened most recently for Survivor set to record at 7:00pm last night (6:57 recording start time). Can anyone determine from the log snippet below what might have been the problem? There was also a recording of The Blacklist that started at the same time successfully, and some of it’s log info is in there at the same time. Thanks.
