Yes, before ubuntu update I tried this command many times and I burned many
films in this way

With one audio it looks the same:

I tried with following scenario:
-I installed ubuntu 8.10 on VBox
-I copied video material created in ubuntu 9.10 by avidemux into machine
with ubuntu 8.10
-I run command mplex -v 2 -f 8 -S 0 -M -o test.mpeg2 test.m2v test_PL.m2a

I tried to run mplex in gdb mode and do backtrace, but this was my first
time using 'gdb' - Is this enough?
