[mythtv-users] Waited 0.2 seconds for data #012#011#011#011to become available

[Brian J. Murrell]

Recently I've started to see these while recording even just one stream
from a clearqam channel on an HVR-950q:

Given that it happens recording even just a single recording and this
backend can record half a dozen programs simultaneously on a busy
night, it doesn't seem likely that this is a resource issue.

Any ideas why it's started happening?  I'm currently using
v0.25-beta-201-g8a5977d on this backend.

Cheers,
