Hey,

Even when I close AnyDVD (and restart MakeMKV) I still get the warning? I rip to unencrypted ISO from AnyDVD, then rip to MKV from that ISO (because I keep the ISO)/

Is that a bug?

Not a bug. Some older AnyDVD versions cause problems with decoding, so MakeMKV squawks whenever it sees the AnyDVD "fingerprint".

MakeMKV does not require AnyDVD to work, and has no control over what AnyDVD does, so it warns you about possible issues beforehand.
