DVD rips (vob files with DVD menus) are not controllable using aMPdroid. Playing a DVD rip takes one to the DVD menu but the aMPdroid remote does not transfer control. Instead you can hear the remote still focused on MediaPortal in the background (i.e. clicking up on the remote moves from Music to Movies, for example). 

Similar to the iPod functionality it would be nice when browsing music in the album to be able to view all other albums of an artist (considering the current album is no sampler) and also to add all albums of that artist to the playlist.

I have found a Bug with the Duration in EPG-View.

When a Show starts at 20:15 and End at 22:20 the Duration is shown as 5 min. This happens with other times to, but for example a show starts at 19:45 and Ends at 20.15, it shows the correct duration.
