System: XP Home Edition Intel Pent. 4, 2GHZ, 512ram DVD Shrink 3.2 Nero 22.214.171.124 DVD Decrypter 126.96.36.199 I have burned 100 plus DVD with no problem. Now encoding takes at least 7 hours followed by 7 hours to burn. This is a list of things I have done to fix problem. 1. Uninstalled IDE Primary/Secondary set to DMA 2. Defragged HDD 3. uninstalled driveres then reinstalled/Updated drivers/firmware 4. Run Ad-aware se, spybot, Norton AV 5.disabled all programs running in background (during burn only 18 processes running) I installed a Linksys USB wireless adapter but I do not think this is the problem. Please help.
