hello,
my objective is to update the artwork on a regular basis to always get the latest and highest rated artwork.
I tried:

Code:

texturecache.py C tvshows @cache.refresh='2010-12-31 23:59:59'  @allow.recacheall=yes @section=salon

and I noticed that it worked for some shows but for other shows, it was caching an artwork which didn't have the highest rating.
After investigation, I noticed that whenever it didn't work, the artwork cached by texturecache.py had a 0 rating on thetvdb (and it seems that when it worked, there was no unrated artwork for the corresponding show)
examples: it cached poster http://thetvdb.com/banners/posters/282670-12.jpg for Narcos (rated 0 with 0 votes) while it cached poster http://thetvdb.com/banners/posters/262407-6.jpg for Black Sails (rated 7.1 and no unrated poster for Black Sails)
I tried to put a note on the artwork and launch the script again, but there is no change in the artwork which is re-cached

1. Is there anything wrong in what I'm doing?
2. If the answer to 1. is no, then I assume there might be an issue with the selection of the artwork to be cached in the script when there is no rating
