Errors duplicating home video DVDs

Hello everyone,

So I've begun the long process of backing up old VHS home videos taken by our camcorder years ago to DVDs. I have used a digital AV to FireWire adapter in the past and had good results. However this time I wanted to try a more direct route.

I have a Samsung DVD-R120 DVD recorder set top box. Basically a VCR, but instead it uses DVD-R discs. So I was under the impression that since these discs are in no way copy-protected, once one disc was finished and finalized by the player (so it can be used in other players) I could just copy the 'VIDEO_TS' folder onto a new disc, thus making copies for family and having backups.

Unfortunately I seem to be wrong. One disc I burned had two videos, and I was able to copy all of the files to my hard drive, letting me make another copy of the disk if I have to. The second disc only had one long video spanning the whole disc. When I try to copy the file, I receive an error saying "The Finder cannot complete the operation because some data in "VTS_01_1.VOB" could not be read or written. (Error code -36)." The disc recording mode allows for 1 hour and 10 minutes per disc (highest quality), all of the discs have been recorded using the same setting.

I look at the disc itself and it is in pristine condition from just being burned, I tired this in another Mac and I get the same error at the same spot/file.

I've tried making an image of the disc in Disk Utility and Toast Titanium. I still get read/write errors. I guess it's possible it could be the disc, but it does play fine and is undamaged. I just would like to be able to copy this DVD, it's taken so long just to make it I'd hate to risk the only copy being damaged.

Any help would be greatly appreciated!

Thanks,
-Steven

Update: I think the problem is with the way the disc was recorded. I recorded four discs in total, both the same length and in the same mode, on the same media. The only difference is, the discs that have issues being copied have one title (video) at 1hr and 10 min. The discs that do copy have at least two titles equaling up to 1hr and 10 min, or one title less then one hour.

It's hard to explain but, think of a title as a main feature. Each title has it's own chapter markers. So a disc can have multiple titles and chapters. I think my only option is to re-record the content.

 

Thanks! That actually worked, it warned me of bad sectors, but it was able to copy it and the disc plays back fine. Thanks again!
