@Madasahat   I think the key element you are missing here is that for me (and others) the Series 6 worked perfectly.   It is not an unreasonable assumption that if you replace your Series 6 with a bigger Series 7 it will work in the same way.   Yes, there may be work-arounds or other solutions but for me I just wanted a plug-n-play replacement for my Series 6. Even the guys in the shop and the shop's technical support centre didn't know of the problem until I demonstrated it. ... View more

I did some research before starting this thread but couldn't come up with anything... I contacted Samsung but no reply to date.   Sadly, the only 'solution' I found was taking it back to the shop and changing it... ... View more

You could be right...   I can't say for sure, but as I mentioned above some files just refused to play completely while others said the audio was not supported.   It is not possible for me to confirm if all the files had a DTS soundtrack as I have sadly now erased the USB stick I took to the store.   However, it would seem to be a completely bizarre step for Samsung - as I mentioned above, every other TV we tested in the showroom played the same files without any issues. ...

Hi,   No, sadly I couldn't see any other soloution other than wait for updated firmware at some point in the future. The store agreed with me too - they tried all of their technical resources and couldn't come up with a solution.   I'd suggest you do like I did, copy a selection of non-working files to USB and return to the store to try and find a display that they will work on. I took a selection that either wouldn't play or that played video but the set said the sound wasn't supported. After demonstrating the problem to the staff the same files ALL worked on an older Series 6 AND on LG and Sony sets. Clearly there is an issue with Series 7.   If it is any consolation, I can't really see any difference in picture quality between the 6 and 7 and I think the base is more attractive and hides cables more easily.   Sorry I couldn't be of more help. ...

Hi,   No, I didn't try any aps as my primary use is streaming from a NAS.   I'm guessing the problem is that it has been released with immature firmware a I noticed a couple of other weird things about it.   1) My 6 Series (40" and the new 50") support 2.4GHz and 5GHz WiFi but the 7 series only supported 2.4GHz.   2) On both the 6 Series sets the files on my NAS are displayed in alphabetical order so everything is easy to find. On the 7 series they were in some bizarre random order so finding the file or folder you wanted was quite difficult! ... View more

UPDATE:   I copied a sample of the files that would not play onto a USB stick and returned to the store.   The files wouldn't play on any Series 7 TV but they would play on any Series 6.   The files also played perfectly on LG, Sony, etc.   After considering all of my options I walked out of the store with a 50" Series 6 Samsung.     ...
