Yep, there was a reason. We have been advised by DivXNetworks to use the
'DivX503b1393p' ID string for better compatibility with their DivX products.
So I'm rather amazed that this change introduces jerky playback with the
DivX decoder. Can you tell us with which version of XviD you've tested? And
which profile was used to encode the video?

bye,
Michael
