Hi all,

I run a pre-show of slides before our programmes (mainly of films coming soon), using .mov files created in FCPX and converted to DCP with DCP-o-Matic. Each different slide is its own DCP, as the order can change weekly as new films are added, old films release etc. It runs as a seamless playlist, at the start of each show.

Having swapped to a new laptop, I've downloaded the updated version of DCP-o-Matic (Version 2.10.5), as was previously using a very old version (likely 3 - 4 years at least). Now, the when the playlist reaches the new DCPs I've created, it hangs for a couple of seconds before playing them, resulting in a blank screen between slides. I've tried creating new DCPs with various different options selected (aspect ratio, SMPTE/Interop), each time had the same result. The content is created at 24fps. The only thing that has changed from when the playlists were previously created is the version of DCP-o-Matic

This is on both an NEC 1200C and 2000C, both running Dolby DSS220 servers.

Has anyone had this issue / know a fix for it?

Many thanks!

Try to reset DCP-o-matic prefs first. What datarate have you set?

DSS220 means CAT745/IMB?

While I do not operate a DSS myself, I monitor the mailing list and forum regularly, and haven't come across such an issue. So, there are some chances that it is not a general bug in DOM, but in your specific installation or settings. Also, 2.10.5 is up for quite a while now. Are you running DOM in WIN, OS X, or Linux?

Hi Carsten,

I've left the datarate how it was set upon install, which is set at 100mbit/s/

Yes, running a CAT745 with IMB.

Running DOM on Windows.

I've just checked the version I was using before, it was 0.74 (running as DVD-o-Matic). I'm going to try an older version of DCP-o-matic to see if my current setup just doesn't like this version of the software for whatever reason.
