The new feed supports OpenATV 5.3 through 6.3, that is 'the last 5 versions of OpenATV'. No need to download the IPK, copy it to the box and installing it through GUI or shell when using the one-liner but you are still free to use an IPK, if you insist on it.
That one-liner makes sure you get the latest version of the feed for your actual image version and architecture. The easiest method of getting a shell session to the box is the 'Terminal' in OpenWebif, but feel free to use puTTy or whatever you already use. If you have an image that is older than, update or flash a newer one first. The softcam control methods in OpenATV changed. This is not a softcam control panel, It just allows you to install softcams from the plugin server.
