- Module is used by me at one Kathrein UFS 923. - Installation problems (duration about 10 minutes). - Module logs each time you turn on new (approx 10 sec.) - Switching times increase in the HD + range of approximately 2 seconds - Timeshift is also possible in the HD + range. - Recording in HD + range can be locked, so basically record in SD. The advantages and disadvantages of the HD + concept has been discussed elsewhere. By extended on / switching times and the sporadic, albeit short, dropouts during playback total remains a negative impression. In addition, since an estimated 96% of the content is no real HD program, but just "Hochgepixelte" Movies are at the moment in the HD + content to the enjoyment also holds very limited. (This also applies to a large part of the 'blockbuster movies "). Would again given the choice the money prefer to invest in a couple of some selected Blue-Rays.
