mpeg2videodec: fix list of supported frame rates to include sane ext rates. 

This only adds a subset of the frame rates that can be stored, a full list
would be more than 500 entries. Such full list could (and should) be added
if it has a usecase but the number of users of even the now added rates
seem rather small.
