My modded xbox won't play all burned games.... Ive made backups of most of my games and only 2-3 seem to work?

I think it has ixtreme 1.4. I have a Samsung Kreon Drive SH-D162 for ripping. I used abgx360 to check the rips. I use IMGBURN to burn them. I use Verbatim DVD-R DL discs. When I put the game in to the system it recognizes the disc, begins to load it and shows some of the intro and gives unreadable... show more I think it has ixtreme 1.4.

I have a Samsung Kreon Drive SH-D162 for ripping.

I used abgx360 to check the rips.

I use IMGBURN to burn them.

I use Verbatim DVD-R DL discs.

When I put the game in to the system it recognizes the disc, begins to load it and shows some of the intro and gives unreadable disc/dirty disc error.

Could it be a bad mod or just because of the version.

Im new to this. Please help

Thank you.
Update: sorry but those first two arent help.

I didnt ask for useless comments.
Update 2: Wow this is absurd.

Backing up my own personal games is not illegal.

ALL REPORTED!
Update 3: I have a lite-on drive with ixtreme 1.4
Update 4: My mistake, they are DVD+R DL Verbatims and always burned at 2.4x.

Yes, I have had 3 burned games work fine, but plenty that won't work at all
