pvrusb2 stopped working
I've been running trunk for quite some time. Last week, I jumped to r20019.
My pvrusb2 stopped working with myth. The pvrusb2 does work, as I can use
vlc to view the output. It seems that myth now wants to do VBI recording,
which of course is not supported by the pvrusb2:

2009-02-22 09:51:02.968 MPEGRec(/dev/video2) Warning: Can't enable VBI
recording (3)
eno: Invalid argument (22)
2009-02-22 09:51:02.999 MPEGRec(/dev/video2) Error: StartEncoding
eno: Invalid argument (22)
2009-02-22 09:51:03.000 MPEGRec(/dev/video2) Error: Failed to start
recording
2009-02-22 09:51:03.003 MPEGRec(/dev/video2) Error: StopEncoding
eno: Invalid argument (22)


However, VBI is disabled on the backend:

mysql> select * from settings where value like 'vbi%';
+-----------+------+----------+
| value | data | hostname |
+-----------+------+----------+
| VbiFormat | None | NULL |
+-----------+------+----------+


I'm at a bit of a loss why this suddenly started doing this. Any help is
appreciated.

Appears that this may be broken in truck as seeing the same problem.
Changes to libs/libmythtv/mpegrecorder.cpp in Changeset: 19989 seem to
be the cause of this. Rolling this file back (and mpegrecorder.h) to the
version before (Changeset: 19857) seems to resolve the issue,
