Some help for people that are having timeout/error problems ..now I have broadband and so far this has worked 100% for me but may not work for everyone so remember what you did before you changed your settings.
RealPlayer Live Feed Playback Fixes
Changing these settings should fix choppy feed problems for most users.
Select 'Tools', 'Preferences' from the menu and then click on 'Playback Settings'. Unclick the Live Pause option, or if you must have it, reduce the 'Live Pause' setting to 5 minutes and unclick 'Temporarily increase this duration' just under that.
Select 'Tools', 'Preferences' from the menu and then click on 'Playback Settings'. At the bottom under 'More Options' increase the playback buffer from 30 seconds to 60 seconds.
Select 'Tools', 'Preferences' from the menu and then click on 'Network Transports'. Check the 'Manually configure' option and then open the 'RTSP Settings' and 'PNA Settings' windows. Uncheck everything except HTTP, leave that as the only transport protocol for RTSP and PNA.
