I use VLC to view live MPEG4 video from video encoder appliances (such as Optelecom or Coretec). In most cases I view video using multicast but sometimes I need to view unicast video from these encoders using RTSP. Up to now I've been stuck using VLC version 0.8.6d because the best i can it's the last version of VLC where the live video didn't lock up after 15-30 seconds. In all the new versions of VLC (tried versions 1.0.*) the video locks up. I'd really like to get away from using this really old version of VLC but I can't until this RTSP issue is resolved.
When using VLC 0.8.6d I see the following RTSP exchange:

There was a bug ticket filed here http://webcache.googleusercontent.com/s ... clnk&gl=si and looks like it was resolved. But I don't have access to some of links within the ticket to see how it was resolved or how I should enable it the 1.0.* versions of VLC. Any ideas?
Thanks for any feedback,
Dave Irwin
