The video standard handling code is pretty much the same in both cases. 
You can use sysfs to dump out a list of all the standards currently 
available (IIRC, it's ctl_video_standard/enum_val, but I will have to 
check to be sure).  Dumping that list for both the in-kernel and 
standalone drivers would be helpful.  Another thing you can do is turn up 
the debugging in the driver.  There's a bunch of traceprint that reports 
what standards are being selected, what's available, etc.  I think turning 
on the "PVR2_TRACE_INIT" flag (see pvrusb2-debug.h for the list of bit 
positions and read the driver's web documentation about manipulating the 
debug mask) will help here.

No argument there.

I'm much more likely to see bug reports here since I don't currently 
monitor the kernel list.  The MAINTAINERS entry for the driver already 
points here.
