I've read "Published App Feed Refresh??" which implies that updated channel feeds are recognized on a daily basis. I recently updated my feed to include 5 new videos. The feed was recognized almost immediately on one of my boxes, but, not others. I typically rename the feed file each time for two reasons:
1. Amazon caches the file so If I don't name it differently, I'll need to wait till they invalidate the cache. I'm not sure they'll do that if the contents change without a name change. 2. I like to keep a monthly feed file using the name of the month as part of the name.
Do I need to force an update each time I update my feed with a different name? Are there any recommendations that take into consideration CDNs that cache their content?
