[pvrusb2] Poor analog picture on HVR-1950 after upgrade to 2.6.28 kernel

[Mike Isely]

Vincent:

Please try one more thing:

> (1) shutdown mythbackend

At this point, power cycle your HVR-1950.  This will cause the pvrusb2 
driver to tear down its state and will also (of course) remove any state 
held by the device.  This way we can be sure that we're starting in the 
same ground state and that MythTV hasn't done something strange.

Even with the above, setting the video standard still should have 
cleared up the stripes and gotten you back a color image.  So power 
cycling likely isn't going to fix this but it's still worth checking.

Still trying to reproduce the problem here...
