[I]PC WORLD labs reports it has unearthed two bugs in Windows XP Service Pack 2, one affecting battery life on notebooks, and the other dual layer DVD drives.
According to the report, SP2 has a negative effect on dual layer DVD drives when running Nero software, slowing down InCD4 burning software by as much as 40 per cent. InCD4 software is bundled with many systems.
The same report claims that some Acer notebooks can reduce battery life by as much as an hour.[/I]
