Hi i have a similar configuration: my Photos are stored on a thecus nas and access from iTunes is via SAMBA. I found out that the actual sort order of the photos equals the order the files are listet by the DIR-command in the directory respectivley. Unfortunately the DIRCMD Option /ON does not work as a workaround.
I tried a lot differnent worarounds:
- change the EXIF-dates
- change the filenames
- rewrite the whole folder
...nothing worked for me.
So it seems to me, that iOS 5 ignores the EXIF-Tags, and ignores the Date and Times-settings of the files and it ignores the filenames.
I would call this definetly a bug.
And of course it is not possible to sort the Potos manually on the iPad in an extra folder.
