Because my Perl development kit is the version only for evaluation.
Muxer function can't be operate in PEnGUIn(Encoder) after Feb. 1.
I will do my best to buy a full version of Perl Development Kit.
(The saddest thing is that it costs 245 dollars.)
I suggest users can adjust the date before Feb. 1, 2007 temporarily before releasing next version of PEnGUIn(Encoder).
Thanks a lot!!
