Otherwise running the dongle. with me on Mac OS 10.4.8 very stable with iTV and the image quality is acceptable. As television stopgap thought the Cinergy met but actually my expectations. On PowerBook is thus possible mobile TV and the included adapters make the device even really flexible. Even cable TV works, with the picture quality, as well as of course improve reception quality somewhat.
For a USB dongle that thing, however, is quite large and heavy and only supported by a female USB connector gravity plays already visible a role, in addition, it is the operation very (very!) Hot, which does not alter the fact that since he was six months work without hesitation.
