[Now playing devil’s advocate]
But what if the digital encoding on the disk is imperfect? He says the pixellation is caused by a scratch, but it is difficult to look at a scratch on a disk and know where in the movie it may affect playback. If the encoding is flawed, the copy will be also. I’ve seen this many times on home made movies/video files, but I’ll admit I’ve never seen it on a commercially made dvd. I have seen encoding so bad on commercially made movies that it appears blocky and has motion blur on fast sequences.[/QUOTE]
If I’m not wrong, even if the original is scratched and the standalone player is not able to recover data, generally (not always) the computer drives are able to correct errors better than standalones, so the data can be recovered safely.
If the scratch is too bad and data cannot be recovered, the drive returns a CRC error, and if the ripping software is not purposely inserting fake data on the file, then that’s impossible at all to rip the disc. But if the file can be read (even if with difficulty), then data on the HDD are error-free.
If the original disc was bad pressed, or the video is corrupted because also the original disc contains wrong data, then the only solution is to make again the movie… Who will pay again actors? :p:p:p
P.S. Sorry Kerry if I misunderstood your post
