Regarding the recordings menu: for whatever reason, the data for the 
contents of that menu doesn't seem to be decodeable on your touch 
device, so you see another menu level (the previous one) than is 
actually active. Are your movie titles use any special characters 
(apart from umlauts) by any chance? Remote Buddy encodes all text as 
UTF-8, so this shouldn't be a problem. But since that text is wrapped 
into XML, an encoding problem might occur there.

Regarding the movies: The movie library is a VIDEO_TS-folder launcher 
and currently doesn't support single files directly. You can work 
around this easily, though, by dragging and dropping the folder 
containing your movies to a location in RB's menu of your choice (in 
Prefs > Menu).

The AJAX Remote password is stored securly in your system's keychain. 
If it can't be stored there, this can have one of three reasons:

1) On Tiger: after an update, when OS X asked you whether it should 
give the new version of Remote Buddy the same permissions as the 
previously used version, you selected "Don't change", an unfortunate 
formulation for "Deny" (a word which Apple started to use only in 
Leopard). Solution: choose "Change all" next time you're asked by OS X.

2) On Leopard: Remote Buddy's application bundle has been modified 
(f.ex. by setting up Remote Buddy under Tiger so that it omits its 
icon in the dock, which requires Remote Buddy to modify its bundle's 
Info.plist under Tiger - and then re-using that copy under Leopard). 
That breaks code signing and has OS X' security mechanisms kick in - 
one of which is that the application will not get any access to the 
keychain. Solution: download a fresh copy of Remote Buddy from our 
website (by clicking on the "Try" button on the left) and replace your 
current copy with it.

3) If neither 1) or 2) solve your problem, there's a third one under 
both Tiger and Leopard, but it's rare: Keychains can get corrupted and 
are then write-protected (so existing entries can be read, but not 
modified - likewise, no new entries can be added, either). Solution: 
repair your keychain. You can check the integrity of your keychain 
(and also repair it using the "Keychain Access.app" (or 
"Schlüsselbundverwaltung.app" in German). The respective option is 
found in the menu of that application. Apple also has a knowledge base 
article on this topic:

http://docs.info.apple.com/article.html?path=Mac/10.4/de/mh1777.html

In all of the above cases, Remote Buddy is denied access to the 
keychain by OS X, which means it can neither read, write, re-write, 
overwrite, delete or detect the password you set for the AJAX Remote.
