The following streaming media forum was very popular
p069.ezboard.com/bstreemeboxvcr
until our forum has stolen the spotlight. The most experienced member of the forum veblin haven't visiting the forum for more than a year. Another very experienced member compn is a moderator of our stream recording forums.

You may also visit the following forum that is created to support software of Applian Technologies, the leading developer of stream recording software:

Other forums that have tiny stream recording sections:
forum.videohelp.com
forums.afterdawn.com

The problem is that this question is more about offline browsers like Offline Explorer Pro. There is no problem recording Windows Media streams, but the slides can't be downloaded easily. IMHO you should find a forum about offline browsers and ask a question in it.

p.s. Unfortunately I really doubt that any developer of stream recording software will make this task urgent.
