There is one failed and one OK site in Alexandre's list that uses a DSS200, so it would be interesting to know if they are pre- and post-4.8.8.4 respectively.
Although the vast majority of the problem sites are Doremi/Barco Series 2 installations, not all of them are, which leads me to speculate that the problem is not specific to that combo, and therefore is either or both of:
1 - QubeMaster Pro is creating glitchy DCPs
2 - The software in the servers / IMBs is out of date.
I'd be inclined to investigate 1 first, because that doesn't require the co-operation of several sites in updating software. I don't know if the local managers would be competent to do that, if it can be done remotely, or if a tech would need to get there, but in any case, there is an element of risk involved in updating server and projector software (the updating process itself could fail, or the new version may introduce new problems), so my instinct would be to explore that second rather than first.
Try making an encrypted DCP using DCP-o-Matic (it's free) with the same auxiliary track configuration that you were using with QubeMaster, and KDMs for the problem sites. It can be short (say, 30 seconds), so that the sites can download it and you don't need to ship media. All you need to know is if it ingests OK and plays OK. Ask the problem sites on your list to ingest it, and tell you if it works or not.
If it works in all the problematic sites, that's pretty convincing evidence that the bug is in QubeMaster. If it fixes the problem at some sites but not others, there could be a QubeMaster problem, a DCP server software update needed, or both. If it fixes none of them, then gather software version information from all the sites on your list, and compare the problem sites with the OK sites. If you see a pattern, update the software at the problem sites. If you don't see a pattern, and/or the problem sites are already running the current server and media block software/firmware, I'm not sure where to go from there.
