I get letterboxing on PCTVTOGO in cases where I don't understand why.  Right now I'm watching Deadwood on a widescreen monitor, with PCTVo go on full screen.  Deadwoodas shot in either 1.77: or 1.85:1.  (This is what I've read; may depend on which season it is.)  Seems like there should be either no or minimal letterboxing,, but in fact it is significant.  The picture is more than twice as wide as tall.  Anyone know why?  Surely HBO doesn't broadcast it in 2.35:1 if it wasn't shot that way.
