copied dvd...errorrs, lifetime?

[chiyoaiki]

I have some copied movie dvd (dvd-5), let call them dvd 'A'. If I make copies of dvd 'A', and let call them dvd 'B'.

I don't know what media is dvd 'A' but I will use Ritex G04 for dvd 'B'.

1). Can dvd 'B' has less errors than dvd 'A', or dvd 'B' can only have as many or more errors than dvd 'A'?

2). Do different medias have different lifetime?

3). Which would be better to keep, dvd 'A' or dvd 'B'?

4). Which tool is best to use to make copy of copied dvd?

Thanks.

Yes different brands of media have different life spans. I'd think if you store them in a dry dark place as well it would last longer. But some really cheap media I've read will fail in as little as 6 month's. I guess you'd have to do your research to get an idea of what media will last about how long. And that would'nt even tell you for sure I don't think. Every individual disk even in the same batch could have a different lifespan I would think.

"1). Can dvd 'B' has less errors than dvd 'A', or dvd 'B' can only have as many or more errors than dvd 'A'? "

Not sure what errors you mean, but if you have copied a dvdr, the copy will be identicle to the original.

"2). Do different medias have different lifetime?"

Yes .... Riteks will last much longer than say Princos.

"3). Which would be better to keep, dvd 'A' or dvd 'B'?"

Better to keep B

"4). Which tool is best to use to make copy of copied dvd"

Easist/safest way is to use DVD Decrypter (freeware) Mode ISO/Read to copy to Hard Drive and ISO/Write to burn.

Hope this helps.
