Loop playback of same bit, is there a cure

Hello guys,
I have just discovered Acestream and am enjoying watching the tennis... quite frequently the playback stops, and when I press play again, I get a repeat of the last two minutes or so, and it stops at the exact same place. I press stop, then play, and again it plays the same section and stops at the exact same place. If I press the LIVE button, it does not help.

Is this an issue with the software or with the stream itself? Is there a cure?

Thanks,
Fred
