Upgradng QSYS VIP to Quartus 14

I have been developing with the VIP suite using Quartus 13.1 for some months, all working happily. I have upgraded to Quartus 14, and all worked fine until I regenerated the QSYS part of the project...

Nothing specific on your problem, but having dealt with similar migration problems my suggestion is to make the 13.1 IP blocks available to your 14.0 project, and then upgrade them piecemeal to help determine the point of breakage. (Qsys14.0->Tools->Options...->IP Search Path and specify your 13.1 quartus\ip directory). If the 13.1 VIP blocks fail with the 14.0 DDR3, that is a different line of investigation.

From your description, I would look closer at DDR3<->Frame Reader behavior since that's where underflow will originate from. You can do easy things like deepening the Frame Reader FIFO as much as practical and see if there is any improvement; or use SignalTap on the Avalon-MM port and FIFO and trigger on the underflow condition to see what happened leading up to it.
