Comment(by isely at pobox.com):
Actually I think there might be at least 2 problems here. I said to
Daniel in e-mail that I would implement a workaround for one problem this
weekend, but I don't have a good characterization for the other problem
(yet).
First Problem: Default GOP size is not really correct for NTSC. This input
to the mpeg encoder happens via the cx2341x module. The module is relying
on the parent driver (e.g. pvrusb2) to set this up correctly. Hans thinks
that the module should be taking on a more proactive role here. In the
mean time (this weekend) I'll see about implementing a workaround in the
driver for.
However that's just the default GOP size.
Second Problem: If mythtv is querying the driver to discover the current
GOP size then things should still work, even with the wrong default. But
apparently it isn't, so there's a second problem going on. I will look at
the pvrusb2 driver and verify that this is being passed through correctly
however I do not know what the problem here is yet. So I can't promise a
fix if I don't even know if the driver is the cause.
