Thanks a lot to IBM for this very interesting release.

Are there some restrictions on the Systems profiles we can use with
XMTBatch, or can we edit freely any XMT files ?
You say we can use DivX to encode the video track, but it seems that AVgen
only supports Simple Profile ( DivX is an Advanced Simple Profile
implementation ).
So, is it allowed to use DivX ASP tools to encode the video track with AVgen
( B-Frames, 1/4 pel, GMC ) ?
Which audio and video profiles are allowed to produce 3GPP compliant content
with AVgen ?

Which Systems profiles are implemented into M4Play ?
Best regards,
Olivier
