[mythtv] DVB & mpeg 4:2:2

I'm trying to watch a 4:2:2 feed from one of my DVB sources and it seems
Myth isn't liking the mpeg2 at all. The tables are all fine and I'm able to
tune, however, the frontend dumps when trying to play it.

Does anyone have knowledge of 4:2:2 mpeg2 in MythTV or know if it's
supported?

This is from the frontend log:
