I am sure I will sound stupid, but I'm completely new to this stuff... I just bought a N810, and I'm trying to install mplayer. Having a nightmare time of it (six hours wasted already!) When I try to install directly using the Application Manager (referencing the extras-devel/chinook repository) I keep getting an error "Downloading mplayer failed". It doesn't seem to want to download the actual install file ("1.0rc1-maemo.23.n8x0"). So then I try to "Install from file" in Application Manager, using the .deb files, and I get an error that some packages required are missing (libmad0, libogg0, libtheora0). So then I try to install those libraries (using "install from file" in Application Manager, and using the .deb files downloaded from the repository), I get an error "incompatible application error". I think I am doing something wrong, but what?!?! Please help a complete noob!
