well thats philosophy 101 sorted with then....
i have wmp11, winamp, imedian and now vlc.
wmp11, winamp and imedian have the advantage of a accessible media library
imedian works great with my wireless remote and is also great for parties with volume control from anywhere in the house
vlc, plays almost anything and as quoted above is clean and simple at 9mb
winamp is skinable but don't really like it for video as you have to click the vid button for the window to open.
do all the mentioned player support 6.1 surround/ 5.1 upmix
thanks for your comments,
josh
