I think if the actual cDvbHdFfDevice::CanScaleVideo implementation would have really calculated something, it should have only converted internally to whatever needed (1/1000 in this case), and back to Osd pixel dimensions before returning the value. Since it doesn't (as it just returns the input rectangle, possibly because the device "is" able to handle any size within the limits, maybe nothing should be changed. Or maybe checking against the limits could be done, changed the size to a reasonable default (like Null for full size) and log an error if the input size wasn't within the Osd limits. Udo's variant looks well, but for all this maybe Andreas Regel should also be consulted. Btw, I sent him a PM on vdr-portal.de, he did not react so far.
