Checked all over the forums and couldn't find anything to answer this. I installed the HD 6450 on an old Dell Inspiron 530 with no problems, however I can play no YouTube videos or iTunes movies. (iTunes displays the HD video window and if I click on a forward moment in the movie I get the still frame...but no motion. YouTube message "An error occurred...") Help! Thanks in advance.
Dell Inspiron 530 (3MB RAM)
Windows 7 Home
HDMI to Sammy HD monitor
No HD video playback
No other issues...typing this on that machine/HD monitor
