Amazon issues

First thanks of all for the great module, you've made very tricky functionality very easy to use!

I had my setup serving the videos from my local server where everything worked fine, I've recently switched over to use Amazons s3 service and I've nearly got it all working fine.

Issue 1: Since swapping over to s3, the thumbnails now no longer load on the player. The jpgs are definitly being created and placed where they should be, they are just not being displayed. In the 'content_type_video' table, the 'field_video_thumb_data' fields are all null if that helps.

Issue 2: When the video node is deleted, the file isnt deleted from the Amazon buckets, this means there will be a growing number of useless files clogging up space. This may be releted to the fact that records are not deleted from the flashvideo_s3 table when the actual node is deleted.

Issue 3: Is there a way to maintain the directory structure on the s3 server? Currently conversion and upload to s3 fail if you specify more than one directory level in the path settings for the content field, eg, 'convertedVid' works but 'convertedVid/[user-id]' fails. This is not a major issue but will lead to poor search perfromance when many files exist in that single file.

Many thanks, Adam
