But about your question. So far, not one firmware update has resulted in more CODEC support. In other words, don't count on it.
A 60 minute call w/Samsung cust. service resulted in massive frustration when I was told the LED TV I bought (UN40C6300SFXZA) can't view m2ts video files but has no issues w/ .avi, .mov or other formats. Short of converting over 5,500 videos (which would take an insane amount of time...like years), does anyone know a solution to this? Is Samsung considering this upgrade in a future firmware release?
