Samsung DVD-HD755 Hi-Def Conversion DVD Player
No Dolby 5.1/DTS through HDMI
This piece of *?^%$ does not support Dolby 5.1/DTS through HDMI.  The workaround listed by the other reviewer is correct, you use the digital Coax for sound, HDMI for video only.  The downsides:    - The delay in the audio makes everything look like poor lip-sync  - Have to switch both receiver and TV when going from cable to DVD  - Extra cables to deal with.  (BTW - the coax signal is digital.  Use the cheapest cable you can get, if it is short).    Another problem: If you put MP3's into it, you navigate subdirectories with names in 8-character format, so the filenames are jibberish.    Got it at Fry's for $69, with HDMI cable.  Not worth it, even at that price.
