[Live-devel] Send/receive MPEG2 TS streams without RTP encapsulation

[Pampolini Matteo]

Hi Ross,

many thanks for your quick feedback.

Currently I'm using Kasenna MediaBase RTSP server, but sigh, my evaluation
license has expired few days ago and I'm waiting for instructions on how to
renew it! So at the moment I cannot tell you what the server answers, but if you
have experience on MediaBase I guess you know it well.

Regards, Matteo
