Schummie,
It may have something to do with the video/DVD/player format you have.
When I was stationed in Germany in the Army, none of our digital clocks (as I recall) worked because the cycles in the the electrical service were not compatible. Our transformers would step down the Germany 220v electricity out of the plug to 110v into our American appliances, but they could not affect the cycles so microwave timers didn’t work, etc. It caused us to buy either German appliances or “dual voltage” appliances with had the appropriate converters (sorry, I’m not an electrician) so support both systems.
As I recall back then (‘83 thru ‘88) there was a difference in video tape formats. Remember that DVDs didn’t exist back then! I would imagine that the differences in systems may have carried over into the DVD format and Norm may not sell a format appropriate to your home in the Netherlands, a simply BEAUTIFUL country, I might add!
He might actually be saving you money! You’d probably hate to buy something you can’t watch.
Cheers!
