Cool :)

Btw. one thing I forgot to mention: after I added the Client via QR Code and then went back into the configuration of the client again, it shows me the "Simple Mode" first, with the Authentication credentials already missing. May be in that instant, when I open the configuration of the client again, everything gets "reset", sort of, due to the TV Server configuration missing or something?

I was able to reproduce it again. These are the exact steps:

1. Opened MPExtended Configurator on the PC with the MediaPortal Client and went to "QR Code" and selected "Include authentication for user: admin"
   
2. Opened the aMPdroid 1.0.1 app on a Lenovo Ideapad A1 (Gingerbread 2.3.4)
3. Went into Menu - Settings - Clients
4. Selected Menu - QR Scan
5. Scanned the QR Scan
   
   • aMPdroid then showed me the "Add new host" window in advanced mode, with the IP address, name, Mac address and Authentication filled in for "WiFi Remote" and "Media", but nothing for "TV Server" (as it should be, since the TV Server is on a different Host)
6. I hit "Ok" to confirm, then pressed "back" until I was out of the application.
7. I went back into aMPdroid - Menu - Settings - Clients
8. I selected the client that I just added
   
   • the authentication information is now gone for "WiFi Remote" and "Media".
   • However, even though "TV Server" was not filled out before, it is now suddenly filled out with the same details as "WiFi Remote" and "Media"

I tried the exact same steps on a Google Nexus-S with Ice Cream Sandwich 4.0.4. The exact same issue occurs there as well.

a) yes :)
b) from MPExtended config
c) Server/Client environment. I.e. TV-Server is installed on Host A, MediaPortal Client is installed on Host B. I installed MPExtended on Host B and used the QR Code to add that Client. It filled out every information, including the authentication. It also filled out the TV-Server part, even though the TV-Server is not located on Host B. After going back into the configuration, the authentication information was gone.

I'll try to reproduce it again, may be I made a mistake somewhere.

It's nice that you can change the default now, but now I want to suggest another alternative :D. Currently you have 3 different default behavior for the single click (Play on PC, Open Info/EPG, Stream).

However, it might also be useful to change the default behavior for the single click, so that the 'long click' pop-up menu is shown. It would make the interaction more quick, if you frequently want to use all of the 3 options and not just one.

Already mentioned here: http://ampdroid.userecho.com/topic/48125-qvga-remote-interface-adjustments/
However, the new aMPdroid version solves this issue, I think.

Fair enough ;)

Yes, but still, I feel the primary action should be to let it play through MediaPortal, since that is what aMPdroid is primarily for. A details view should be a contextual action.

In version 0.8, the default action for video files, in the share view at least, is streaming to the Android phone. Imho this should be changed, since aMPdroid is primarily an application to remote control the Media Portal client. Or so I thought ;).

Also, you can change the order of the groups (including all channels) within the TV server configuration. I guess aMPdroid is displaying it in that order as well, so when you move another group to the first place, it will display that group first.
