Hi. I have a 1.33 12 inch powerbook that I love to death. It runs great, but whenever I try to burn a video DVD on roxio toast. It takes almost an entire day to encode and when it finishes, it says I have an error 50. Im not as worried about that, but after I did this, my airport connection got very dodgy. It would only work if I was very up close to the wireless router. This has happened to me once before. After using the same program, I began to have less airport connection and then my computer got slower until it finally wouldnt boot into the OS. Apple repaired it because it seemed to have a failed harddrive. I thought my problems would be over but now it seems that they are about to start again and I am scared that I will lose my hard drive again. What should I do? The airport works perfect a couple feet from the router, but when I get about 10 feet away it completely dissapears. Can anyone help please?
