This thread is specifically for those who are trying to understand the Playbars 5.1 and DTS issues.
As most of you know the Playbar does not convert DTS signal. It also will only convert 2.0 to SIMULATED PCM 5.1 signal. If you can live with the simulated signal, then you are ahead of the game. IF you want PURE unadulterated 5.1 from your DirecTV or Cable, you WILL most likely have to buy a switch like this one. http://www.monoprice.com/products/7974
Or a Bluray converter like this one.
MOST tvs will not convert true 5.1. There are some on this thread that say they do, but most dont. I found this out the hard way by buying one of Samsungs highest end tv's, only to find out that 2.0 is all im ever gunna get.
A $75 switch is a bargain IMO to have such sound to the Playbar the way it is intended. IF you want 1080p up convert video and and 5.1 audio, then a simular Bluray like the Oppo is for you.
Concerning movies that are only on DTS:
Oppo can convert the DTS signal to PCM 5.1 as well. I do not know about the Switch, because I do not have one.
