Does sony dru-700a have terrible 1x capability?

heres the scenario. i ordered a crappy brand of dvd-r’s because they work great on my xbox. i patched the vy06 firmware for 1x on most -r but when i burn at 1x i get failures. the disks are 2x but sometimes i like burning at 1x to test for differences. i have a 1x dvd-rw that burns fine but i cant get a clean burn on -r at 1x, only 2 and up. anybody else try this or know of a reason?

Looks like you have found the difference :slight_smile:
