Same person soz changed accs last night.

Thanks for the reply.
So I guess the reason why some play some don't is down to the codecs which 
means a 32bit rebuild or will I have the same problem with some wmv3 
playback. 
Am I right is it down to the codecs as wmv3/wmv9 is normally asf which means 
it's likely to contain other formats. I'm still left a little confused why 
some play some don't but as you said natively I guess its down to the code.

I also suspect now the reason for not being able to play indeo 5 is because 
really the codecs don't exist on 64bit, though installed and looked for.
