I saw xine, ogle mentioned in a step by step guide 
(http://pvrhw.goldfish.org/tiki-page.php?pageName=rh9pvr250) and just 
installed it.  When I did my playback (video only) started working so I 
thought...
That was my problem, I thought...  Should my Hauppage 190 be similar to 
the PVR250 as far as this install is concerned?

I'm curious, why was an "internal player" used/created instead of one of 
the many available?  I hope that's not a dumb question.

Is sound required to see the video?

I'm now hearing sound when I attempt live watching, so I thought I had 
sound licked...

OK, Thanks I'll keep plugging away at it and post my resulting 
successful procedure.  And thankyou VERY much for the support!  Are you 
the author of any of this great stuff?
