I hope this is the correct forum to post this ?, if not, please let me know.

Here's the ?:

I have a old video file in VIVO format. Vivo has been taken over by REAL but they don't support this format anymore (?x!@).
So there is no player available to convert this file in any way (to my knowledge).
I worked about 40 hours on this file but lost the original AVI.

Does anyone has any tips on how to make this file playable again so I can start encoding it into another format?

Since I don't want to be a cross poster I would appreciate if you would give me the correct forum to post this question in, if this is not it.
