I can no longer burn dvds on my pc's dvr. I can open files and play from my dvr (e drive) but when I right click, send to, it does not show up as a path. I had work done on my computer a while back and that is when it stopped. I told someone about the problem and he thought it might in something like codex stuff. How can I get it back? Wha can I look for as a problem maker? Help Please.
