Makes sense.

and you should be able to get better startup times I guess.  I've been very 
impressed with the vdr-xine quality with DVB - except now I'm using 
pvr-input on a PVR-150.  This is only a temporary measure until I get all 
the bits to build a DVB-S system.

I'm using a Shuttle PC with an s-video out.  Since this can't be used for 
HDTV, maybe I need to look at getting a TV with VGA input - or find an 
RGB/Component card and buy a budget DVB-S.  That leaves me with a PCI slot 
shortage.  Hmm, maybe I need to rethink all this....

Thanks for your help, by the way....
