This is a workaround for how Lost in Time behaves in combination with changes I made to the DataIO code for running Urban Runner on low-memory devices. Urban Runner's intro are far to big to have them copied into memory for these devices, so I made the DataIO code return a SafeSeekableSubReadStream into the opened archive stream instead. Unfortunately, Lost in Time might not close a video file when it closes the data file which it was originally in, especially when loading a saved game. Since the video player needs to be able to gaplessly continue a video and there does not, by itself, close the video if not requested by the scripts, this leads to reading out of an already closed stream in certain cases. So, to worka round this issues, the video player tries to reopen each currently opened video after a data archive was closed, to make sure that that video is still available. If not, the video is closed.
