Could someone clarify whether the Dish PVR 721 is supported by OpenTV? If not does someone know WHY not? As all other PVRs from Echostar are supported and Echostar and OpenTV formed a joint-venture called OpenStar for the development of advanced PVR settopboxes. If the 721 is not supported yet by OpenTV, will it become so if the foreseable future by downloading an update for example? I know OpenTV is supposed to be able to run on Linux. Thank you for all who are able to supply some answers concerning this matter.
