hi, good day to you. i indeed use original dvd and original purchased xbox 360 disc as well, but it just wont read it anymore,

the best part, i use to play the exact game on my xbox before this and now it just wont load it anymore. example like battlefield bad company which i played and completed the mission previously with the same console, now when i try play the game again ,
it just wont read the disc anymore.

this goes to all my xbox 360 disc which is original and all my movies too.

i purchased original lord of the ring movies dvd set and it doesnt play it too..

It wil read dvds and some of my xbox one games. Blu rays wont play at all. Sometimes it takes few tries of putting the disc in and taking it out but eventually it works or atleast it used to. I inserted titanfall 2 and it started right up. Ill try an xbox
360 game in the morning. I can hear the disc drive trying to read to the disc but eventually it stops. Ill report my issue to the insider club as well. Hurry up with the scorpio already and i wont have this issue

Here are a few troubleshooters you may want to look through. the most common reason and Xbox 360 won't read a disc is if the optical lens inside the disc tray area that actually reads the discs is dirty. But these should help any ways.

The best way to get that fixed if that is the issue, would be to either clean the disc itself with a soft cloth to make it easier to read or to take the console to a local electronics hobby store like a GameStop to get it cleaned up. Microsoft doesn't do
servicing for Xbox 360's anymore and its really advised to not try and repair/clean up a console yourself.

How do you know it wont read old 360 discs?

They are just DVD's after all.
