Troops: since the upgrades to RealPlayer are not backwards compatible, this is the cause of these problems. I have tested the archived files using RealPlayer 11 - for this selection (only!! to my knowledge) Real possesses full functionality concerning your noted issues. I suggest that this be the release of Real that you place on your PC. Should you still encounter problems, the back row of PCs in CFD Lab, Perkins 317, have been set up for full support of ME 452. Attached are the directions for viewing video files. Elton Freeman, who set up these machnies, is copied hereon for reference. AJB A.J.

Can anyone else use the streaming links or rewind the lectures, or is everyone having similar problems? Spero Peters
