Does the Micosoft's ASF container format have also been standardized by
SMPTE while standardizing VC1 [ wmv9 ] ? 

Or all the VC1 products have to use MPEG2 TS ?  I am having this doubt coz
while checking out on various encoders for vc1 / wm9 

The o/p card/module is optional and can be  in IP Ethernet ASF or  can be


So , is it because SMPTE standards of VC1 says that wmv9 video must be
within MPEG2 TS only ? 


The only concern is .. say if someone deploys  low end WM9 based solution
from Microsoft today , will he be able to migrate to 

High end telco grade VC1 based solution later on ?   that too without much
of an hassle since  VC1 and wmv9 is exactly same ?  assuming that audio
codec would remain the same After migration ?
