Problems playing video files on extended desktop

[billyo]

just wondering if you're using a pc to tv/monitor adapter, the reason i asked was that this adapters are not really good enough to play music videos , i bought all kinds of adapters, installed all kinds of codec.( vdj has a list of diff. codecs).downloaded videos from hd to low quality resolution..nothing help..problem still exist when playing in fullscreen, minimizing the screen to about 3/4 to all extended monitor helps and a lot it decreases my cpu usage, since music videos does takes a lot of cpu power.. i think the only solution was to get a very powerful graphic/video cards...
