You've got a stack of Region 2 DVDs and a Region 1 player. The temptation to flash a hacked firmware or enter a secret remote code is real. Don't do it. Here's why the risks outweigh the reward, and the legal, hassle-free alternatives.
Laptop/HTPC → HDMI → TV. Play any region in VLC. Use a wireless keyboard/remote. Most flexible, zero hardware mods.
Don't flash firmware. Buy a $100 multi-region player or a $25 USB drive + VLC. You get perfect playback, zero legal risk, and 4K streaming apps included. The hack isn't worth the headache.
