Thanks for your reply.
I think that mp3 is a questionably choice since it is not opensource and 
has some license fees.
Actually Opus is the only opensource, royalty-free project and that 
seems to be very adactive, optimal for both lan and wan.
For what concerning IE, unfortunately IMHO is a bad browser, in 
particular in the implementation of the standards.
In the past when I was doing web programming it gave me a lot of 
problems, so best bet for a good choice of a decent codec is to leave IE 
concernings at all.
Lets focus instead on better implemented web browsers like firefox 
and/or chrome instead.
