Q. Will my current copy of
Replay Media Catcher change?
A. No. If you've installed Replay Media Catcher 3.01 prior to January 28, 2009, no new plug-in downloads will occur unless you delete the old files on your PC.
The above answer is totally incorrect!!! The new plug-ins are disguised as "plug-in" updates without any information as to the new limitations of the program.
