I seen some DVD Players for Sale ,That State they Play XVID.

Now I havent really looked into the XVID origin.But the thing I always hear is that it was a "Hack" of DIVX. Is this true?

I see XVID falls under (GPL).

So is it Legal for them (Stores) to advertise that a certain DVD Player Plays it?

I know that DIVX Is a licensed "Codec" "Software" Company,and May have arrangements with the Companys that advertise the (Divx) Name.
