How do you test a media? and what software do you use?

[tamasdragon]

I mean what kind of tests do you usually do to test written dvds. And with what kind of software?

thanks

DVDinfoPro, Nero CD/DVD Speed, & kProbe. Please note that kProbe requires a LiteOn drive to work.

DVDInfoPro only works with certain drives too, unfortunately it's the cheap ones it works with. All drives will do CRC errors, but only a few do PI, PO and jitter tests.

I've seen this question asked quite a few times in the past year. I've tried all the above listed programs. They work, but they take as long to check the disk as it takes to write the disk. I don't have the technical expertise, but over time, I have found that for my own collection of disks what works best for me is to run the newly created disk thru WIN DVD and using the slide bar, run it back and forth the length of the movie as quick as possible. If the movie doesn't hang then it's more than likley ok.
More importantly, if it doesn't hang you can always re-copy from that disk.
I have looked for another quick way to check a disk but haven't found one.

There are three things to check.
First: whether the data was correctly written on the disk
Second: will this disk be readable by target machines (standalone players).
Durability: Will the media brand withstand harsh handling, minor scratches and heat?

For the first test, I rely on the recording s/w verify. Actually, I only skip the verify step when recording RWs for proof viewing. All final media is verified. Failure rate is close to 1%, but this 1% can get very embarrasing.

For the second test, you need a player that is known to be incompatible with media recorded out of specs. I used to have a yamakawa player and when it died I got myself a Denon. Some of my early DVDs are not playable on that - although they play perfectly on the PC with s/w players.

For the third test, well just record a cartoon movie and give the disk to a kid to play with. Joking. But doing some rough handling on the media, actually touching the recorded surface and letting it rest on a TV for a few days, to collect heat and dust, is good enough. Some media brands failed even this simple test - this is how I devised it
