Complete patch with recent improvements

Fixed a crash that occurred when the manifest file contained more than 1024 fragment run table entries
Return EOF instead of looping back to the beginning for non live streams
Cannot assume the first fragment number will be zero

Ed, I was able to reproduce the crash with the information you sent.  Thank you.
I fixed it and sent an updated patch.

If you're able to test it with your setup, please let me know how it goes.

Cory

Had a thought on this one. This will only work when fragment_entry is the only entry in the fragment table. Otherwise fragment_entry->first_fragment will be the wrong number sometimes.

In this case fragment_entry->first_fragment should probably be replaced with abst->fragment_run_table_boxes[0]-> fragment_run_entries[0]->first_fragment (i.e. the fragment number of the first fragment entry). I'm not sure if this takes the selected segment (if any) into account though.

Regards,
Ed
