[mythtv-users] can't change channels on PVR-350

some more information, in case anyone feels like they can help us out:

I tried just running ptune-ui and selecting channels with that and got  
some output (that I had previously believed to be from mplayer):

XS_Tk__Callback_Call error:Error:  changeChannel(6) failed!

Tk::Error: Error:  changeChannel(6) failed!
  Tk::Widget::Callback at  
line 1079
  Tk::BrowseEntry::LbChoose at  
BrowseEntry.pm line 296
  Tk::BrowseEntry::ListboxRelease at  
BrowseEntry.pm line 163
  (command bound to event)

Once again, anyone who has any ideas, please drop me a line.  I have no  
idea what I might be doing wrong, and Google searches have not proven  
to be terribly useful.
