make sure your rendering in WMV format....i havent used WMM in ages cant remember if you have to change that or not with it.....vegas is 200% better ive been rendering my films in 720i 1024x768HD wmv format converted to divx. youtube drains a ton of video quality and files cant be larger then 100meg.A 3-4 min video rendered in HD usually requires 120-160megs.
