there is a limitation through the bandwidth that passes through router 4K

1. I try to watch 4K movies through DNLA, the movies come out distorted and of poor quality
2. 1080P movies work great through DNLA

why is it happening ?
1000mbps router bandwidth
trying to transfer from computer to Blue Ray Sony 800m2

Re: there is a limitation through the bandwidth passes thro

No, there's no DLNA related issue here. I watch UHD ripped movies on my network all the time using the Nvidia Shield as the player, which has wired Gigabit Ethernet. But remember that all connections in the network must support Gigabit. Your Blu Ray player most likely only has a Fast Ethernet connection, which maxes out at 100 Mbps. My Roku devices also have that limitation. You could try using WiFi, as an 802.11n or .11ac connection would in theory have more bandwidth than Fast Ethernet, but it's also susceptible to interference that can reduce speed.

But that is your problem, in that the Sony doesn't have a Gigabit network connection. My ripped UHD movies have bitrate peaks over 150 Mbps, which is why I can't watch them with my Roku players. And of course, your computer has to have a Gigabit network connection as well. Depending on its age, it too might not have a fast enough network card.

Maybe because the computer also downloads files to a mechanical disk it degrades performance ?

Other programs accessing the hard drive could certainly impact streaming performance. But it's tough to say without more detailed analysis. However, you're identified the choke point, in that your BD player only supports Fast Ethernet. If you're playing an uncompressed UHD movie rip, it simply can't keep up with the video bitstream. But it does support 802.11n, which in theory is capable of 150-300 Mbps. That should be sufficient for UHD rips. But again, your computer must also be capable of streaming at that bitrate. So check your computer to see if it support Gigabit Ethernet (1000 Mbps), If it doesn't, you'll never stream fast enough from the computer for UHD rips. But in most computers you can add a new network card, and Gigabit cards don't cost much.
