Check DVDs for errors?

[Mikel30]

I'm in the process of ripping all my DVDs and creating masters. Some of my DVDs have light to moderate scratching. Is there any application that can scan a DVD and show any damaged areas that will produce read errors (and playback issues)? I would love to ID those now, rather than months down the road when I'm trying to watch something.

I think most ripping apps just stop when they encounter a serious error, at least thats been my experience. So if the rip was successful I think the video file would be OK. A fast scan will sometimes error where a slow read does not.

Well at the moment I'm just using Disk Utility to make a DVD Master. Then later I'm going to use something like Handbrake to actually convert them. If possible, I'd like to catch the read errors at this step, the importing, rather than down the line when I'm doing the converting or viewing.

I'm thinking disk utility will stop too (if it can't read the data off the DVD), but you may want to try it on a known bad DVD.
