Custom cover art for individual TV series episodes

I know about this: Metadata 101 – Firecore

But there’s no mentioning on how to deal with multiple episodes in the same folder. Let’s say I have these in the same folder:

show-name_s01e01.avi
show-name_s01e02.avi
show-name_s01e03.avi

My problem is that the artwork at thetvdb.com is wrong, so I want to manually override this. Is there a way to do that? The most obvious way would be:

show-name_s01e01.avi
show-name_s01e01.jpg
show-name_s01e02.avi
show-name_s01e02.jpg
show-name_s01e03.avi
show-name_s01e03.jpg

But that doesn’t seem to work.

What to do?

I have been having the same problem. Your methodology worked like a champ for me on ATV Flash. It is not working for me on Infuse for ATV. Perhaps in your example above, each episode, image file, and .xml file (if you so choose) needs to be in a folder all its own? When I get home tonight I am going to try this different method. Seems painful to have to take that extra step, but Infuse for iOS clearly uses different algorithms than ATV Flash.
