Comment (by grzesiekb):

 Hello again.

 For telling truth - I used vim :). I include summary of communication
 below, I think it is quite clear:

 Don't use this summary as strong reference - I removed some important
 parts (like authentication problems with VLC) - you can read those pcap
 files in Vim for example. As I said - I can send complete files on email.

 It is clear that VLC + Live555 doesn't send GET_PARAMETER and
 GET_PARAMETER is problem in this case.
