hi,
when i render in any WMV template (only tried WMV at the moment because i want it in HD for youtube) it wil either come up with a error message, stop working, close down, freeze , or say debug or close programme and its always and 23% or 29% in the rendered video it will wok untl a specific point in where a few of them the music cuts out and stops,could this mean its a audio problem . is there any formats for youtube which allows hd rather than wmv, i have formats in the whole project of m2t/mts2 in pal 1080i hd and a .mov file(i have rendered this before with no problems) i have also rendere other projects exactly the same as this with no problems what is causing this?
many thanks


( i now have tried to render in .mov and got to around 60% and then it closed down due to a unkown error)

an error has occured during the operation
