Samsung HT-C6530 Home Theater not able to play 1080p DTS MKV files, but..

[scansbar]

Hello,
I have spent tons of hours and days trying to figure this out so any help or explanation would be greatly appreciated.

I have a Samsung HT-C6530 Home Theater System that is able to play 720p MKV files that are encoded with the DTS Audio codec on a DVD disk, but it is not able to play 1080p MKV files that are encoded with the DTS Audio codec on a Bluray disk as the audio stutters and then it is mute.

I tried it on a LG Bluray player and it can't play it either.

Now I'm assuming that the players can't decode the DTS so my only option is to encode it with lets say AC3 and it will work.

I don't understand how it can play the 720p and not 1080p. Is it because there is too much data to process?

Any help or explanation would be greatly appreciated as I can't figure this mystery out.
The Bluray players advertise that they can decode DTS.

Thank you for reading and hopefully you can assist as I'm backing up my movie collection and before it grows I'd like to know what are my options.

Take care
Mark

My first thought based on the stuttering, would be that it doesn't have the processing power needed to process 1080P AND DTS audio.

there are different levels of DTS. use mediainfo on the file that plays and the one that doesn't and post the text results.

720p takes a lot less processing power than 1080p. A few years ago I had an old single core CPU PC that was capable of starting to play 720p H.264 before crapping out. It couldn't even start 1080p H.264.

Saying it can decode DTS does not mean that you can put DTS in any old file with any possible video and it will work. I agree that it's deceptive, but it may just mean that DTS is supported on DVD and BluRay format discs and iffy on everything else (maybe it works, maybe it doesn't).

This is quite possibly the real answer. I have a sony bluray player that plays mkv with dolby digital 5.1 a-ok but won't play any dts tracks. However it is very specific of which type of video and audio it will play when playing files. I have to have the dts in a m2ts file which I haven't tried yet. It SHOULD work according to the manual. You should go cover to cover on the manual and see if there are any rules on which file types it will read dts in. It might be locking dts out of mkv files. A simple remux to the file type it will support should do the trick. Good luck. Edit - I also don't know if any of these restrictions are due to the bitrate of the dts files. I only have dts from dvds or bluray. The dvds are usually always 1.5mpbs I believe and the blurays are at least that much - not sure what dts-ma is off the top of my head. However as I don't know if there is a freeware dts encoder I can't reencode to something like 750kpbs to test if its a bitrate limitation on the file playback side. Edit - sorry I tried to edit in spaces between paragraphs but it didn't save it for some reason.
