Does skipping mean data loss?

[infexious]

I am currently backing up my DVD's to fairly cheap discs, I don't need to be able to play them in my set-top DVD player so skipping doesn't bother me.

However am I correct in thinking that the actual data is a perfect copy even if the media isn't capable of being played back perfectly.

Basically if I have a problem with any of my originals, I'd like to think I could use these cheaper discs to create a perfect copy on more expensive media.

Thanks...

This is not bad question... I was thinking about same problem. I know that cheap media can be problematic in playing DVD movie in standaloene player, but what about data backup.Can I be sure that my computer data backup are going to be accesible when I need them ??? Or is this problem same for data ???

If the disks play OK on your PC but skip on your standalone the my guess would be that you are right. It is just the ability of the reader to read the data from cheap/poor media that is the problem and there is no actual data lost during the writing process. As long as you keep these copies in a suitable environment (clean, dust free, sensible temps etc) then they should be fine for re-copying to good quality media for years to come.

computer dvd-rom's are built with more powerful lasers than set tops.

That's why cheap dvd players play so much so well, APex just mounts an IDE DVD-ROM with a decoder board.



You can use cheaper media to clone it, however any imperfections will be cloned as well.


Try playing it or using it in ur comp

I get skipping on my PC's DVD drive aswell, but if I copy the files to my hard-disk the skipping appears to go away.

I assume that the cheap media just makes reading slower (hence the skips), but that the data itself is still a perfect clone.

I would appreciate some kind of clarification on this though... if anyone knows the whole story that is...
