Chrome Browser initiated player Quality

This Directv player that I initiate from the browser via the directv guide is horrible.  The resolution is low quality, it freezes and repeats over and over, is slow to start.  What a piece of crap.  No, it isn't my internet connection.  I can watch 4 simultaneous HD youtube videos at full screen without any glitches.  Yet this tiny non-fullscreen player is horrible.  Also, the way the system works is not desirable.  It should work like a channel changer, not a pick a show mechanism, as the default.  The player should stay open, not restart each time you change "channels".  Substandard software at its worst.
