My friend gave a DVD (DVD-R) to me with videos (sets of vob, bup, ifo files) on it, and I tried to play it on my PC (specs: AMD Athlon 64 x2 4400, 2gb ram, asus a8n-sli premium mobo, 160gb hitachi sata2 HDD, Windows XP PRO SP2) with a DVD-RW drive (NEC DVD-RW ND-3540A).
The first few files are fine until I hit one that seemed to be damaged. The player (WMP, Real, DivX, Nero…) just crashed and some gave me a reedability error. Later I confirmed that it was the dreaded CRC error.
I tried to play the disk on another comp’s DVD drive, but no avail. I’ve also used CRC recovery software, attempting to fix the bad sectors, still no use.
In frustration, I just popped the disk into a regular DVD drive that was connected to TV. To my uttermost shock, the DVD played PERFECTLY, as if there is no error at all! The part that caused readability problems on my PC did not affect the playback. FYI, the player was a Toshiba SD-3960.
I am now confused. Why was the disk able to play on a regular DVD player but not on PC? Maybe it was something to do with the optical drive? or the OS? Also, since the DVD is obviously not damanged (playable with a regular DVD player), is there any way to extract the video without hitting another CRC error?
