Have a problem;)!
I have Canon PowerShot A540 that can make video clips and that works OK and clips are in AVI format, I did not see that it can be changed on camera settings,
I replay clips on my camera and I can download and play clips on my PC.
When I wanted to free up some space on my HD and back up my video files I found an issue.
All files that were copied with Nero as Data DVD (so no file conversion) were copied and burned to DVDs without burning errors, but when I tried to play files from burned DVD video was OK, but sound had some short sound distortions repeatedly every several seconds which makes copied files useless for backup that I wanted to have.
Nero will correctly convert and burn video DVD with same files, but that is not what I want.
I just want to copy files from my HD to DVD in original format.
Please let me know if you have any ideas why would NERO have issues burning AVI files to data DVD.
I do not think this has anything to do with recording media, I got the same result when I was using DVD or when I used CD.
