If the second lavc overrides the first one, how have I been getting mpeg2
files till now which could be burnt on DVD? I am so much amazed. Is mpeg2
default format for lavc? That means my KDVD matrices were not working till
now? And is toolame better them lavc's mp2?
I am now even more eager to go home and test my script with one lavc rather
than two.

Please reply
