Performance product but improvements

This recorder responds fully to the principal function: save up to 2 programs simultaneously, if necessary by watching a third simultaneously. Menus are reasonably straightforward, although they could still be simplified (without loss of functions). DVB-T reception is pretty good (especially by the built electronic signal amplification): Television multiplex France Eiffel Tower (France 3) was frequently lost-frozen (especially in case of nebulosity) on a Sony TV end antenna cable (pavilion: the loft on the ground floor). The MS450H signal recovers to 90-95% of the time (now 100% by shortening the cable glands of 4-5 meters in the house and putting the new cable).
The points of improvement: the rate of automatic scrolling of photos is not configurable; portrait-landscape shifts made under Windows are not considered (everyone turns his head 90 °); the procedure for rotating photos of 90 ° is galley-longuet ...
The wireless receiver is positive (Youtube, etc) but it is underutilized: copy videos between 2 MS450H must be through USB key disk (wifi not available).
I also find it lacks in range a model with DVD recorder (to avoid draining the memory via USB hard drive and PC). I have not yet attempted to connect a DVD recorder to the USB jack but I doubt that it works (drivers ...).
Overall: satisfied with the purchase, within specifications.
