Did a little debugging under XP in Vmware. Found one bottleneck and an error. Seems that the python sendresponse http method is kind of slow under windows, so added a simple hack. Also you have to use O_BINARY ( what is this shit…) for lowlevel fileio under Windows. Was able to stream a DVD from the Vmware Windows. No Stutter, everything smooth.Hope that Windows User are happy now ;-)
