I'm still running this, and it's still an integral part of my media center setup. For the last month or two, I've had to tweak almost nothing of it, and that's awesome.
Ran into one issue today, tho, and here it is:
I changed my config for show quality. I wanted to get Colbert and Daily Show in HD, as I don't really bother archiving them for long any way - so I added this line to my Quality.config:
The Daily Show|720p
Same for Colbert. Now, it happened yesterday that there was no HD version of Colbert on NZB Matrix or any of my other feeds. That meant I simply didn't get that show downloaded, and I'd have settled for a Divx version in that case.
Any way you could fix it so it would prioritize A, but download B if A was not found?
