What happened?

when there are multiple entries for a program episode only the first entry gets season & episode info.
The info is present in the raw data received from Schedules Direct

What did you expect to happen?

All episodes to contain season & episode.

Did you see any warnings/errors?

None.

Any other information?

I did some debugging and I think what happens is that in get_program_episode when the while loop parsing meta data is exited by the last metadata if $is_gracenote; command the iterator for the metadata hash is not reset then the next time it is called not data is returned.

I am not a perl programmer so I'm not confident this would be a final solution but adding:

keys %{$metadata};

before

while(my ($key, $value) = each %{$metadata}) {

cured the problem for me.
This is related to changes for #222

Thanks
