Just wanted to give an update here.... Using the kernel suggested by @CHBMB I was able to get my SageTV to recognize my 2 HDPVRs and last night it appears to have recorded a couple of shows and they appear fine.
I'm still fine tuning my docker image, but once it's done, I'll see about getting it added to the Community Applications plugin (tried finding some info on how I do that, but it's not apparent, yet, how I 'submit' a new application)
I've been playing around with docker + wine for the comskip piece. Adding in wine adds a gig to the docker container size, which while large, its still not too bad. It appears that wine 1.8 does play better with docker. I was able to fire up a container with wine 1.8 and run comskip from the command line without any errors.
