The best way for me to describe this problem, is to retell the story of how I discovered it:
I dual boot Windows and Linux. On Windows I use CloneDVD2 (188.8.131.52), and on Linux I use mainly DVD Shrink (184.108.40.206) running under wine.
Every DVD I buy, I backup the original, store it away, then only use the backup from then on. I nearly always watch my DVDs on the PC, since my monitor is actually bigger than my TV
I haven’t been keeping track of which tools I used to back up the DVDs at any given time (didn’t think I needed to), until now.
I recently started watching my DVD backups using a standalone player (NAD L55), which is a very nice $800 machine, but was horrified to discover that some of these backups were “corrupted”. Specifically, the scenes jump, the picture jitters, the audio screeches, and it’s generally unwatchable, in spurts throughout the movie.
However, not all of these backups exhibited this problem, so I set out to discover the difference between the good and bad backups.
- All HQ media (Verbatim, TDK). I.e. MCC 03RG20
- No correlation between media and errors
- All burned on the same drive (Plextor PX-716SA)
- All 16x media burned at 8x
Then I finally made the connection…
Every single one of the “corrupt” DVDs had the following “Application ID”:
“ELBY CLONEDVD” !!!
I’ve been through my entire collection of backups (only around 100 so far), and 37 of them are CloneDVD backups, and without exception every single one exhibits this “corrupt” behaviour on this NAD player.
Now like I said, these backups work fine on the PC, so what is the most likely explanation for this problem. Remember … same media, same drive, same burn speed; the only difference is the backup program???
Is CloneDVD’s MPEG encoding broken?
