Yes, I tend to not report things until I can create a mostly
reliable reproducer (I have been on the "other" end of the such
reports for long enough to know that if I can not reproduce
the failure, I am never going to feel I can properly validate
a fix).

I see in one of the TODO lists
  http://www.isely.net/svn/pvrusb2/tags/mci-rel-20100424/doc/notes.txt
the comment:

   o What is this all about during initialization of HVR-1950: "
      pvrusb2: failed to grab control of dtv input (code=-1)" - this
      seems to randomly happen.

Sounds like Mike understands the issue, and now he just
needs to be able to find the time to address it.
