I purchase this unit because I want the 4 hdmus switching and think I would stick with Samsung since I like they display . the unit have decent feature and a attractive design . however , after set it up I discover that when view content from my dvr , if I pause , rewound or forward the audio would take 4 seconds to sync up . the Samsung be replace a Yamaha receiver and I do not have this issue with the Yamaha . I also have a problem with the unit not remember any setting I program -lrb- memory would wipe when power off -rrb- . I contact Samsung support via email , and do not ever receive a reply . I return the unit to Amazon and replace it with a Onkyo system that I have have good result with .
