Trouble playing dvd iso

Help and Support
1

Having a weird issue. I have two Vero 4K+ units. One plays a dvd iso fine and the other one does not. I tried checking all the setting and didn’t notice anything different. It starts to show the dvd intro credits but when it goes to dvd menu screen I just get a black screen.

My other unit shows the menu fine.

Here are logs for unit that is not working. Is there some special add on I need to play dvd iso menus?

It would be helpful if you also post a log set from playing this ISO from the Vero, which shows no problems.

Thanks I edited original post to include both logs.

Very strange! this is where it gets very different:

why is the CFileCache::Open - </media/Media/Tools/Dolby Atmos 9.1.6 Speaker Test/> opening action?
Are the ISO files identical?

Currently I have no idea how to interpret that.

Hmm yes the ISO file I am opening is same. Under /media/Media/Tools there is a folder named Dolby Atmos 9.1.6 Speaker Test but the ISO file is not in that folder. Its just a file under /Media/Tools

It seems the working Vero uses SW decoding

whereas the not working Vero uses HW decoding

Would that be the Accerate MPEG2 option in settings? I believe I had them both set to Always.

8

Yes, we’re using HW decoding only for HD streams.

I moved ISO file into its own folder and it appears to be working now. Now I am experiencing buffering issue on all movies while my working unit works fine. I’ll create a new post after I search the forums. Thank you for your help!
