There is no such thing, css is removed at the ripping stage (extraction), not the burning stage.

Abrown15 asked you if you use a *sofwtare* called AnyDVD, not if you used "any blank dvd disc" - because this software removes css in the background when you rip the original DVD.

I'm not familiar with CloneDVD2 but from what I understand it seems to need an app like AnyDVD to handle some copy protections. Read about this in the "Copy DVD movie" section of this site.

BUT, as the playing gets "glitchy" only after a while, I still suspect a media/burning issue. Does the playing skip or freeze also? This is the signature of a bad burn. On what burner and at which speed do you burn your Ridatas?
