I've been doing some experimenting with this with the following results - - recompiling the psyche cdrtools-1.10-14.src.rpm and running that on shrike gives solid cd writing. - using the shrike cdrtools with my standard burn command produces rubbish; either a blank that hasn't been written to or errors in the burn. - using the shrike cdrtools with my standard burn command on a cd rewritable blank is solid. Odd. - using the shrike cdrtools with tha addition of the "driveropts=burnfree" statment seems pretty solid so far. Even though the message comes back saying "BURN-Free was never needed". Odd.
