after saw your post i said ****, man!!!! sorry to say that but your windows is messed up good. i propose clean install. slipstream sp2 into your xp cd and install.
like u mean that windows longhorn will be sp3 for xp?? first of all every new windows is new.... mean it comes with new features compare with the old one.so a new win can not be a service pack......
sp2 brakes things when is installed over a previous instalationof winxp. if u slipstream it also with the last updates (i recommand ryanvm packs) it works great. don't listen to any rumors......
i supose that u have an iso. i burn it on a dvd using dvd decrypter. hoe to do it: start dvd decrypter click mode>iso>write then just indicate the program where u have the iso an hit the burn button. that is it..... tried and worked!!!
for general files like .avi or .mp3 or some others u can use dfx plugin. u find it here: www.fxsound.com. or for dvd movies only if u use wmp u can use ac3filter.
well it looks just like clasic 32bit win xp. it just runs a lttle bit faster then the 32bit version. the only problem is the drivers on 64 bit cause they are just like win 64bit beta.....
