When my same ZM system was running version 1.22.3, the fast forwarding worked fine.
After the upgrade to 1.23.1, if set the rate to 2x -4x, when viewing an event, it doesn't appear to be any faster than realtime rate 'real'. The 10x rate only seems to go about 2x. If I set the rate to 25x or 50x, the rate only goes about 3x-5x.
Fast forwarding is slow in both the new DVR viewer and the standard event viewer. When I'm in the standard event viewer, the progress bar appears to be accurate with the fast forward speed even though the video stream is not.
I looked at the logs and I don't see any error messages of any kind. I tried changing from zms to nph-zms but that did not have any effect on the fast forward speed.
I'm using Ubuntu 7.10 server. I made the 1.23.1 build with the lastest ffmpeg from the svn

Does anyone have any ideas why fast forwarding is the working as fast as it should for me?
