QuickTime 7 cache files are saved to subdirectories of ~/Library/Caches/QuickTime/downloads/ QuickTime 7 cache files (.qtch) can't be opened and played; the binary format differs from previous versions. If that trailer can be viewed with QT 6.5, then you could use that to save it as a file, or, there are reportedly web pages set up that will save the stream out as a file for you. In any case, your difficulty is a feature (doubtless demanded by content owners) of QuickTime 7, not OS X 10.4. It functions the same way under 10.3. On Sep 2, 2005, at 12:04 PM, B.
