The videos downloaded since I installed the Beta prior to 5.01 release, and the current 5.01 release (I re-installed twice, to the same effect) play out heavily pixelated in all three platforms I use - Real Player, Windows Media Player, and Windows Media Center. Until I installed the beta and 5.01, have never seen this occur before; also updated the converter (#3) several times. It is not the players listed above, since I tested all three with older converted videos.
