I bought a 812s to burn 4x DVD-R minus at 8x (like I was able to burn DVD+R at 8x on my 451s@851s).
Upgraded my 812s to 832s. works great (THANKS to codeguys!). more media are supported. so far 4DVD+R burns at 8X are improved.... BUT still no joy on 4x DVD-R @ 8x (last part of DVD has corrupted video. :sad:
codeguys, will 4x DVD-R @ 8x fix be doable for 812s/832s?
