hi chris, i can see your stream to port 17038 on my windows XP laptop with openmash vic--rather a ghostly sight! the other stream i tried viewing with standard vic on my SGI and it took forever to come up and display (like maybe 3 minutes!) but it did come up with two images--but too slow to be useful. however, those standard streams come up ok on my windows box so it must be me. i can see the Physics Presenter and Main windows just fine. however, no one's there so i can't see how the motion quality is. i don't have the rtptv client so i can't see the higher resolution. -gurcharan =========================== Gurcharan S.

Could anyone check whether these streams are visible please? 233.2.178.9/17038 is an RTPtv stream, also viewable with OpenMash vic 233.2.178.9/17018 standard vic stream Than chris --- end of quote ---
