Re: Is a TRT test a valid way of testing the readability of a disc?

The disc scored zero and the TRT was afu'd so i throw it in my set top player and no problems watching the DVD video.
The bad TRT in your desktop drive proves that the desktop drive has problems reading the disc at full speed.

Watching the DVD with no freezing or skipping in your standalone DVD player proves that the disc can be read without major difficulty at normal playing speed in your standalone DVD player.

These are not mutually exclusive results; in fact this happens quite often.

There is no such thing as "meaningless" files for disc quality scans and Transfer Rate Tests; the drive and the software don't care what those files contain - only whether they can be read and how many correctable and uncorrectable errors are detected by the drive's error correcting layer.

If you can read a DVD by performing a TRT, you can also copy the files from that DVD using the same drive (provided that your harddrive has sufficient free space); The TRT actually reads the data on the disc, it just doesn't write the data to the harddrive.
