I have a strange issue streaming to my Samsung UN46D7000 TV. A few observations:

(1) DVDs ripped to MP4 or MKV with Clone DVD mobile stream without error to my D series TV.
(2) BR DVDs ripped to MK4/H.264/AAC with HandBrake cause my D series to reboot as soon as streaming starts, unless....
(3) If I pre-transcode the BR MKV, it streams without error to my D series.
(4) The larger MKVs (without pre-transcoding) stream without issue to my Samsung UN65ES8000 TV.
(5) If I use the Mezzmo android client to push the same file to the D series, it plays without issue (but appears to transcode).

Any ideas?
