I've got sky plus and I just wondered what stations I would be able to receive if I bought a Sky HD box off ebay and plugged it in. Does anyone know if the HD free to air channels would become available, or do Sky need to be involved in any way? I don't really wanna pay their subs for the HD service as I wouldn't want to watch any of their premium ones. Cheers if you can help. Oh, also, is any particular make superior? I noticed a Thompson one going for a lot less than the Samsungs, but maybe that was down to hard drive size...
