Doesn't have to be weather per se. It could be wind moving nearby
trees, it could be a plane flying overhead in the wrong spot (!). Such
are the vagaries of trying to accurately receive a very dense radio
signal like ATSC.
That being said, given how you're already using an outdoor antenna
mast, unless you're very far away from the transmission towers (you
*have* checked your address at <URL:http://www.antennaweb.org/>,
right?), the issues I mentioned above tend more to affect people like
me who use indoor antennas; the SNQ level says as much.
Rereading your original message at
you describe the issue you face as either/or: Either the episode gets
recorded correctly, or it doesn't get recorded at all, which only
happens if the initial signal lock never gets completed,
period. Assuming I'm interpreting your description correctly--that you
never, or almost almost never ever, see several seconds or minutes'
worth of video missing from some of your recordings, which in this
case would almost unquestionably be a sign of intermittent reception
issues--as ke-myth sagely observes in the thread, what you are facing
could very well be a backend (more likely) or HDHomeRun (less likely,
given your use of new firmware) issue. Having no experience with
MythDora I am at a loss.
Frontend/backend: P4 3.0GHz, 1.5TB software RAID 5 array
Slave backend: Quad-core Xeon 1.6GHz, 6.6TB sw RAID 6
Video inputs: Four high-definition over FireWire/OTA
Accessories: 47" 1080p LCD, 5.1 digital, and MX-600
