How to make playable .RMF format RealVideos?

$

Some old videos I would like to check on, are in RealPlayer .RM format. 99,99% of them play fine, all one need is to install just the RealAlternative (w/o the browser support it is pretty slim package) and things work just fine, even on Windows 2000 SP4 and old BSplayer 1.41 :) So far, so good. However I get plenty of vids that are .RM by extension, however inside the header look quite different AND they refuse to play in anything I tried yet.
So after some time battling with this alone I decided to go and ask, if there is any conversion tool, that strip the weird header and make these play as normal .RM files, or do I need to re-encode them (I fear loss of quality) to be able actually play them back?

The header look this way:
Code:

Anyone have any idea? Preferably... replace the header? :D

PS. tried to replace the header, the file play, but as a very small size vid AND there is nothing visible in it and the sound is just crazy and so... So change of the header make it possible, I just need to do it right :D

On a side note, the video is not exactly for the fainthearted, so, beware when trying to play it...

PS2. GSpot failed on the video:
