Replay Media Catcher keeps stopping recording Ustream after 1 minute

Hi all

I'm trying to record a ustream channel http://www.ustream.tv/channel/mogra1 with a lot of difficulty

the channel id is 2738931

the other url for the video is http://www.ustream.tv/flash/live/1/2738931

when I click that it generates:-
http://static-cdn1.ustream.tv/swf/li...931&vrsl=c:644

When Replay Media Catcher saves 1 minute flv, I right click it and it gives me the following:-

rtmp://r449463455006480.1.2738931.channel.live.ums.ustrea m.tv:1935/ustream

For whatever reason, replay media catcher just doesnt want to record one continuous flv file, it records a minute or more video then stops. I've also tried WM Recorder 14 and that doesnt work effectively either, instead of recording 1 flv file, it keeps making new flv files every few seconds.

I'd really like to record the broadcasts so I'm hoping someone can shed some light, ideally I want to avoid having to use the screen capture thing.

Hope someone can help, if you need any more info please ask.
