I am starting to think that the issue might not be signal loss. My signal strength is at 100% and signal quality is up around 90% and the few times that I've actually had trouble with losing signal the screen goes blue and says "there was a signal loss" for a few seconds until it comes back.
It happened again tonight with the biggest loser. 2 hour program, huge 13gb file, but it shows up as only 7 minutes long. Has anyone had this problem? Is there a log somewhere that I could check for more information? Any other forum I should seek out for help?
