Is it possible to install PlayOn!X with all packs similar to the semi-official firmware? Is it available?
Yes you can. it is avaliable. Look at firmwares, alternate firmwares and you will find it. It installs fine and has a cool web interface. http://playon.unixstorm.org/installation.php has all the details.
I saw the link. But it says the optware and RSS packs require a hard drive. I was hoping for a flash-only install similar to the semi-official package. Is there anything else the PlayOn!X gives over the stock ACRBO if the packages are not installed?
