Several years ago we found out that the PS2 is a great replacement for the commando remote.
We burn all of our DVDs via Nero and all of them play flawlessly on the PS2.
The PS2 controller allows you to:
Jump to chapters.
The thing I really like is the controller allows you to jump back and forth very quickly when you are watching game film.
PS2 currently go for about $45 on Ebay and a Commando remote is still a couple of hundred dollars the last time I checked.
For me the smart money is on the PS2
UPDATE: I just check the Gamestop website and used PS2s are going for 50 dollars.
