HDPVR works fine with the DVB builds in the latest beta. Even the IR blaster works once the firmware is added, which I think is something CHBMB will address.
However, a couple of gotcha's :
You must change the permissions yourself via the go script, since the DVB pluging doesn't know about /dev/video0.
If the HDPVR requires a power cycle for whatever reason, it may not come back as /dev/video0 so the docker will fail to start. Probably could be resolved with some udev rules.
The SPDIF audio sync issue is a problem in Linux but not under windows. Supposed to not be a problem with RCA jack audio.
Can't run comskip under wine under Docker. Something to do with 64 bit.
Hope this helps.
