Last change on this file since 315 was 315, checked in by Nicholas Riley, 16 years ago

StreamVision.py: Added more support for recent appscript versions
(k.Property => k.property). Removed unnecessary .get invocations
since we've dropped support for older appscript versions where it was
required. Robustified RealPlayer support.
