First of all please don't add an unrelated post to an existing thread, start a new post.
I assume that you mean Setanta which is encrypted in Videoguard. The encryption has not been broken so you will need to obtain a valid subscription - there are no codes.
I don't know the tboston 4600 but I don't think it will understand Videoguard. You will need a Digibox or possibly a suitable CAM if your receiver has a CI slot. But beware if you go for a CAM as $ly are issuing new cards shortly and no-one knows if they will work in CAMs.
