Quoting you PM to me: < I have 512K and 4G on hard drive. >
Do you mean 512Mb or is it 512Kb? If it is 512Kb then your RAM is definitly not enough. If it is 512Mb then it's more than enough. My only doubght goes to the CPU, i'm not sure if that will be enough...
4G is not enough if you need to first create a DVD folder to the hard drive (ex: movie transcoding).
PS: next time reply on the thread, and not with PM ok?
