Hello. I've heard that some tests on CD-Freaks and other places, have proven that burning ISOs at lower speeds actually increase PI/PO errors." Is this correct? I was thinking burning PSX games at a low speed was better. (even necessary?!) How come a PS1/PsOne CD-ROM drive which has only 2x read speed i guess, would read a CD-R media got burned by 52x speed?
Low speed was never necessary. There is a limit with cheap burners and cheap media though. Things can vibrate a big much at high speeds causing misalignment. In any case, a crappy drive at 1-2x drive will always produce a shittier burn that a good drive at 5 or 10x. I did a lot of experimenting with this burning PC Engine disks. Those are notoriously finicky. I'd guess that drives are calibrated for higher burn speeds from the factory, since thats the speed 99% of consumers will use them at. I've seen that the faster drives don't even let you select speeds below 4x. And the read speed has nothing to do with the burn speed. It only matters that the data is burned acceptably.
When burning ritechs mini dvd's on a pioneer for gamecube, if you do it at 1x or 2x then they fail. Only 4x works. No idea why. Also back in the c64 days, there were tapes that nobody could copy. But if I used the high speed tape to tape then they worked fine.
