I always wondered why my palm cannot play certain mp3 files. I suppected that it's the copyright bit in mp3. So I picked up my rasty c programming and try to code a small program to invert he copyright bit. But before that I'll need to search the loction of the bit in an mp3 file. Finally I found it in google, and finally I coded a program to do so. Then I found that it still plays no matter what the bit is. Wasted the whole day. But it made me realise how bad my c programming is. Mr BLOG
