Why does this happen? (video flicker - games unplayable)

[xretrogamedevx]

I bought an OG xbox and around 10 games. The discs play fine. Upon loading them to my HDD about 5 of them do this weird video flicker thing and are unplayable.

I tried downloading the same 5 off of sites (isos and xbe format) and FTPing them and USBing them via FATXplorer. Nothing I do seems to work.

Does anyone know why this is happening and how to fix it? Thank you.

Edit: I can't figure out how to delete post. Fixed it.

Got it working... I had to patch the games and I finally found the right script.  It was a problem with 480p on version 1.6.

Still dealing with major lag though.  I can't figure this out.  Makes me motion sick it's so bad.
