Confused, as usual. What do I need to make Mezzmo work with surround sound?

I have posted several questions and the more I research, the more I am confused. I bought a LG bp620 that time is running out for return, but now I don't know for sure what I need. I have an Onkyo HT 340 that does not have HDMI. I have been trying to play .mkv files that show to be DTS and AC3 files in them. I am running fiber optical from player to Onkyo. The video is great but all that shows up in 3/2.1 DTS and Dolby Digital. The folks over at AVS forum tell me that LG does not support DTS through DLNA. What about Dolby? I don't really care about DTS. To me, it is uncontrollable on volume outburst. I know most people prefer DTS but I am the oddball that does not like getting the sound level set and all of sudden a gunshot or explosion rocks the whole house. Is DTS considered different in the fact of pass through on DLNA? I want to play .mkv with Dolby 5.1 though my system but do I need a different receiver? Will HDMI on my receiver fix this or is something DLNA is just not allowing on all receivers? I have not been transcoding because I have tried that and it is still not 5.1. I have asked for Directv profile for 5.1 and have not received it yet, but from what I am reading, Directv is no different on allowing it. What do I need to be trying to get 5.1 from DLNA? HDMI receiver or get a different blu ray player? I know this long but I would appreciate some of the gurus weighing on this. I am running out of time to return my LG.
Thanks in advance,

I'll let other Mezzmo users provide their specific advice & experiences with their particular receivers. I'll tell you about DLNA. The DLNA guidelines have no restrictions with regards Dolby Digital, DTS or 5.1 audio. Any audio restrictions/conversions that you are experiencing will be from the hardware manufacturers. My *guess* is that your receiver is the limiting factor in your home theater setup. If possible, it would be great if you could try another receiver (make sure it has HDMI & HDMI/ARC) and see if that is the case. Worst case, you should try to have the possibility of returning the new receiver if it proves not to be any better. Good luck!
