["Malcolm Surgenor" <malcolm@xxxxxxx>]

I asked the following question in another forum...

-----
I have a downloaded movie that plays fine in Windows Media Player. AVICodec
identifies it as an XVID MPEG-4 file which according to the manual your
product supports.  When I play the movie I get the error message Q Pixel
Not
Supported and can hear the sound track but can't see the picture.  What
does
this mean please?
-----

In response I got this reply, the only bit I really understand is
"definitely not supported".

-----
Hi Malcolm, it meant what it says, QPel is definitely not supported. Also,
XviD's 3 warp point GMC also cannot be supported - DivX's 1 warp point GMC
however is supported. We've tested using XviD V1.00 Beta2 with GMC, QPel
disabled. BVOB however have been tested up to 2 along with the packed
bitstream option enabled.
-----

Given copyright and encryption issues with movies, DVDs, etc I'm always a
little hesitant about asking these sorts of questions (in case I'm in
breach!) but just what does the response I got mean?  :-)  Are there lots
of
different DIVx / xVID standards?
