Problems with very BIG .iso files...

[Harmonium]

All my movies are .iso files. They are 1:1 backup of the original. They all work pretty well except the ones that exceed 70 GB. For example, Dune - Part one (2021) 90,66 GB, Pacific Rim (2013) 80,97 GB. When reading the files I have a lot of hiccups with the sound. Dune is aware of it but support is very very slow. I sent my first message on September 2021 and the last answer I had from them is November 2021. And then nothing. Does anyone else has the same problem?

No don't have that problem. My HDD's are USB3 attached.

No such problems here - i have many movies with Dolby Vision in ISO format with 80 or 90 GB on a Synology NAS!

Have you tried with the Dolby Atmos audio track?

[Nice Monkey]

Of course.

I have tried with other players and I don't have the problem!

Have you tried with the movies I listed?

[Nice Monkey]

I normally watch my movies using a Zidoo player. Have seen those movies but most likely using a Zidoo.

A friend always uses his Dune Pro Vision and never complained about this and he is extremely critical.

I have seen some stuttering with DV+Atmos+External subtitles but could not reproduce it when asked by Dune anymore. This was several FW updates ago.

Have you tried a different hdmi cable ?? mayby hdmi bandwith problem ?? dune to tv or dune to av then tv is av got a good enough hdmi spec to pass high bitrate data ??

[Harmonium]

I have pretty good HDMI cables but I didn't try another one! But when I stripped some audio tracks to go below 50 GB it was working ok!

where and when in Dune part one does it cause problems ? list here and ill check my version

[isolar801]

Dune 1984 4K is the real torture test....88 gigs in filesize at around 90mb bitrate. my Real Vision plays it perfect on a USB connected drive with Zeskit HDMI cable.

or mayby this is a iso/bd menu problem, as yes i also have files around the 85 gig mark and not noticed any problems streaming from my synology nas

I have an Asustor AS6604T with 4 Seagate IronWolf 12 TB...
Using English Dolby Atmos track, it begins between 00:01:00 and 00:02:00 (So at the beginning). I have 4 hiccups. The next one is at 00:19:00...

Dune plays fine here, you didnt fully say how you got your player hooked up, try HDMI video direct to tv, and HDMI audio to your AVR, my avr wont pass the video for some reason ( well too old for new HDR ) and i get a red fuzzy screen ,

[Nice Monkey]

Many old(er) AVR won't play DV (just HDR10) and even fairly recent no HDR10+ which requires dual HDMI Output to be used.
