Coming back to an older thread.
I just started to play with proxmox/kvm, so maybe a little advise is needed.
I did setup a new machine from scratch, proxmox 5, with debian 8.8  
guest in vm.
Installed mythbackend from source.
Using DVB-C USB Tuner (TechnoTrend TT-connect CT2-4650 CI v1.1)

I see a lot of artefacts like in this screenshot : http://imgur.com/a/uYeOv

have been running on bare metal for ages, (different host, but same  
tuner) i do not see those problems
I do not find any "USB Tuning" parameters for proxmox.

any thoughts ?

thanks
