When you download and install Media Portal from the plugins download list and then reboot and press the Plugin button you will get an error: Some plugins are not available: Extensions/Mediaportal (no module names argparse) to fix this do the following, I use a windows PC not sure how you do it on Mac, someone else may comment on this. Works on my T3 and T4 so now reason it wont work on T2 also.
* First you will need to know your T4 IP address, with your T4 remote go into Menu / Information / Network and find your IP, should be something like 192.168.1.xx
* On your PC Click on start and run Command Prompt (I just type cmd into search and it opens)
* When command prompt opens type in: telnet yourt4ipaddress e.g. telnet 192.168.1.16 and press enter
* Next you should see beyonwizt4 login: here you just enter the username which is root and press enter
* Now you should see root@beyonwizt4:~# and here you want to type the following line and press enter: opkg install python-argparse
* You should see some activity in the command window such as downloading and configuring
* when it has finished it will again show root@beyonwizt4:~# now simply type in reboot and your T4 will reboot, you can now close command prompt and Media portal should now work again
When you first go into Media Portal it will probably ask you to update, just follow the on screen prompts, enjoy
