The MBone VCR can record and playback RTP packets.
RTP is the Real Time Transport Protocol which provides
basic real-time media communication support and it is
used by a variaty of MBone applications. MBone VCR is 
compatible with RTPv1, RTPv2 and the vat protocol (RTPv0).
(RTCP is not yet supported but will be included asap).
The MBone VCR will synchronize the packets based on information
in the RTP packets and recover the original timing during
playback. It supports sessions of virtually as many media
as one wants to specify.
