Question:
Can anyone provide an explanation for this -- I posted a thread about the problem before recently but I don't think anyone believed me!
I bought a Sony HT-K25 sound system for Christmas (I have a Samsung 709 player), and it's fine otherwise, i.e. I really don't think that I haven't set it up properly.
But I've noticed on R1 DVDs that accessing the DTS track is causing a lessening of picture quality -- it isn't that noticeable with things which are close-up, but from medium shot downwards, everything loses its sharpness and seems a lot more pixellated than before. Particularly detailed backgrounds start shimmering like crazy. DD5.1 is okay, no effect there.
If I was a bit more au fait with DVD terminology I might be able to better describe the effect, but basically everything loses some of the quality it should have and starts to look (a little) like a VCD.
I'm not sure if it's doing the same with R2s or not -- I'd say not, but I haven't watched that many of them yet, and perhaps the sharper resolution of PAL means I wouldn't notice it quite the same.
I've experienced this with the R1 discs of E.T. (2002), Die Hard and the Scorsese Cape Fear.
I must reiterate that this is honestly not just my imagination, and it's a real pain! I suppose I don't have to choose the DTS track but if the facilities are there...
Time for a new DVD player perhaps? Any help is much appreciated.
Very strange - although the 709 was famous for having some compatibility issues with some discs depending on firmware versions, and it's an old player now.
I don't recall reading anything regarding DTS only though - I assume that you've tried the DD track on the same discs that are giving you trouble? Given a preference I'd use a DTS track over a DD one where available, so I understand your frustration. Trying to think how the soundtrack could affect video though....
Cheers for the reply Radiohead.
I have tried the same discs with DD, and they're all as good as you'd expect -- no effect at all with that option, just with DTS.
I haven't a clue why this is happening...
As DTS uses a higher bitrate more often than not than the DD track, it could be that the 709 has succumbed to old age and is somehow struggling to cope with the bit rate, thus the picture stream is getting the grief. One test would be a Superbit disc, to see what happens there.
