They are not wrong. 
The "normal" WinTV DVB-S card does not deliver the original PES header
for the channel which is currently display, only the elementary
stream. The PES header and TS packaging you get from the driver is a
reconstruction. I have no way to know the real ID used in the original
TS. So, I use 0xe0, the first possible video ID.

The Nova card delivers the original TS packets. It seems that some
channels use other video Ids like 0xe1, which is allowed according to
the specs. So, just change VDR to allow the whole range of video IDs.
