Mac the Ripper Crash


Greetings All,
I'm experiencing an odd problem with my Mac the Ripper program. Of late, the program crashes when in use (for entirely legal purposes I hasten to add) while trying to rip unexceptional dvds. I'm using OS X 4.11 (granted very old) on an eMAc, so I'm wondering if this is a hardware problem. Any thoughts from anyone? Thanks loads, Sparrowhawk.
