Hello, a bit more information on this issue

Just for information, Here I attach you the log of another test I did,
the CAM answers the list of available Ids several times (each time you
change it basically) on the same session.

Manu : the test in the libdvben50221 was intended to deal with which case ?

I notice also that the decoding can fail if the PMT_ASK is sent between
the two ca_list answer at the beginning (this is a bit boring).

Regards
