USB Dongle Network not possible on your device easily. Because Kernel is not compiled with Network Support too. You needed to recompile Kernel with Network support. Then USB hack will make your TV connected to network. Possible to use of Samba/NFS mounts then.
Hack does not allow PIP support. I don't know where to change for that hack. If some one where to change that PIP thing enable, than I will put support

Thanks.
