This CD will run even if any codec is installed at the computer you'll play
I guess you wanted to say no codec, but I'm afraid you're wrong. Did you really test your CD's with a DivX5 movie on a fresh installed computer? I beg not! :twisted:

Look at the bspfilters.sam, there is a warning!
; FilterGUID - Filter GUID that you wish to add, filter must be installed

When you register, in it's latest v5.02 under WinMe, those CLSID are added to registry:
HKCR\CLSID\{78766964-0000-0010-8000-00AA00389B71} -> "DivX Decoder Filter"
HKCR\CLSID\{310E42A0-F913-11D4-887C-006008DC5C26} -> "DivX Decoder Filter Properties Page"
HKCR\CLSID\{1ADD57B8-A7A9-4518-B9B5-862590FF9EB4} -> "DivX Decoder Filter Help Page"
HKCR\CLSID\{83E66439-05D5-488C-A236-AA20E543D384} -> "DivX Decoder Filter Quality Page"
And the decoder is added to the DirectShow filter enumeration:
(But when you unregister (DivX5.02), last CLSID_DivXDeux instances remain.)

I've compared the log of registry access from BSplayer (running on HD a movie located on HD), before and after registering the filter v5.02 located in the \filters directory.
When BSplayer don't find in the registry, at HKCR\CLSID\ the DivX Decoder Filter it has to load, as specified in bspfilters.dat, then it fails playing a DivX5 movie.

What you say was true for DivX3. For DivX3 movies, you just have to put in the \filters dir without registering, and it works (even with no bspfilters.* files) ...Magic! You can't access it's properties in the movie context menu, it's *really* not registered.
Move the codec in an other directory, it won't play anymore: you get the famous "unknown file format (DIV3)"... or DIV4.

:arrow: FFDShow is maybe the solution, as it can play every DivX file. But I've made no test. I'm not shure it can perfom as well.

The \filters directory magic don't work for DivX5 codecs, even with the help of the bspfilters.dat file you would get the "unknown file format (DIVX)".. But put the divxdec codec whatever you want, register it (with regsvr32.exe) and that'll be OK, even for DIV3 movies.

It doesn't work anymore for DVobsub neiher. I was used to put in the filter directory, together with Vobsub.dll, and register DVobsub, but I have some trouble now to make it work everywhere without installation.

-> still inverstigating...
