some of the plugins like 1channel and icefilms, while its not the actual plugin thats the problem with them no longer working, its a nightmare for the plugin creators to keep up, and its down to UK ISPs blocking the filesharing sites that they rely on for the files to be streamed from
you cant actually 'extract' just specific on demand service plugins from the OE-A ondemand plugin, as its been created in such a way that so many parts are reliant on so many other things that this would be impossible
afaik the itv plugin released by subixonfire still runs as a standalone plugin, the the latest BBC iPlayer standalone is v0.4 , possibly listed as v4, but im sure i uploaded it to DW, ill have a look on my linux PC later for them
