1. I tried with 2x, 4x and 20x and had the same error
2. The disc is in very good condition I cannot see any scratch or damage
3. Yes in the following weeks I will scout ebay to get one and compare the dumps

4. Unfortunately I don't have a second drive which supports 0xC8 instructions
Also when I dump the disc with IsoBuster and the same Plextor drive the image has the same size but data is different (different hash).
When dumping the disc with IsoBuster and two different drives I get the same image file (same hash).
