Reimar, I think you raise the key point. The position values may be wrong as 
index_entries are added. I will be providing sample files as time goes on. 
Trying to take this one step at a time. If the problem with positon values 
occurs because of improper framing, then it would be great if some kind of 
fix could be found for this. If not, it would probably be better not to add 
index_entries if a guess is being made on that.

The thing I am looking at now is index_entries and how they are supposed to 
relate to key frames and this appears to be broken in some cases.
