Ok, I'll give it a shot!  Having read more of it in the last couple of
 days, I've gotta say, it's a pretty impressive compendium of DTV info.

(Nope --- in my head I was thinking along the lines of, say, differences
 in board layout affecting RF performance --- but now that I think about
 it, they all have an F-connector coming out of the same tin box, so there
 should be any difference at all on that end.)

If the cx88 driver were to catch up, any prognosis on whether the cx2388x
 chips would somehow fare better than the bt878A?  (It seems like DTV
 functionality was hacked onto the bt878A, whereas the cx2388x series
 were redesigned with interfaces dedicated to DTV --- but it's not clear
 if or how this makes an impact on *today's* boards/applications.)

Yes, thank you!
