First off, I don't want to know where you got the movie from in AVI format. :disagree:
Next, you say 'and converted it into my hard drive in dvd format'.
How did you do that and exactly what format did you end up with?
Save your discs, they're not the problem. I suspect that what ever format you converted the AVI file to, is not compatible with any DVD player, which is why I'd like to know what you did, and what you ended up with.
