[AG-TECH] Release of AGVCR - recording AG sessions

Thu Nov 10 10:29:11 CST 2005

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 and rat starting.

I am not sure what I am doing wrong. Attached is a snaphot.
Note the "File Offset: .....out of 0 bytes" ????

TIA
Monika
