I just completed a test session with the folks at

well until I switched venues from the one in which I
made the original recording. Playback then worked
well. Just as with recording playback does require you
to have a multicast session active and join into the
multicast group with the configuration in AGVCR.
Playback while still in the original venue caused
broken audio from the other remote sites and I could
not hear any of the playback audio though I could
see the video playback as well as the continuing live
video. This is on a Windows XP Pro SP2 in
multicast. >

Hi All,
I am currently trying it on XP Pro SP2 with
multicast. >>Recording seems to work fine (the file
got some size). >>When playing back, I don't see vic

I am not sure what I am doing wrong. Attached is a

Win XP Pro SP2. Works like a charm in multicast.

Hi Zsolt,
Yea, that's one thing noted in the 'known issues',

can communicate off-list on the best way to get the
recordings to you. AGVCR is a program to
record and play back the RTP/RTCP stream that an
AccessGrid conference uses. The amount of data it
gathers is certainly non-trivial, a few hours of
recording with a number of participants can easily
reach a few gigabytes in size. Timing and minimal
overhead information is embedded in the

I invite anyone interested to take a look,
download and use it to see
what you think. I welcome feedback, please bear in
mind though that it is still being actively worked
on. >>>>A number of changes have been made of late, so

but that's another reason to get it out there. The

for popular Linuxes if there is interest. >
Thanks,
