Problem Ripping DVD audio to CD audio
A friend asked me to rip the audio only from a DVD live ragga concert
which he camcorded and converted to DVD. I used "DVD Audio Extractor" and "Audacity" to do the job. DAE reads the DVD and shows the chapters which you can play in order to decide whether it should be ripped. This utility will save audio to wav, ogg, and mp3. Once saved I read the wav file (in my case) and convert the format from 48khz to 44.1 khz, and strip out the music portion to save. All was working well until for some unknown reason my DVD drive wouldn't read this particular DVD anymore. It sees other DVD's, but not this one. I checked for rootkits and found none. I examined the disc surface and it's perfect. I rebooted several times and each time the DVD drive reports empty. The first time I only saved 8 out of the 19 songs on the disc. When I went back to get songs 9 thru 19 the DVD drive says empty. Anyone have any idea what's happening. Thanks -BP |
I would bet for a rootkit even if you already checked.
What did you use ? sysinternal's tool ? Did you try hijackthis ? |
@Dialhot,

I hardly believe he would have placed a rootkit knowingly on this DVD. :roll: I used the following: 1) Black Light F-Secure Beta 2) Windows-KB890830-V1.16.exe 3) Rootkit Revealer RootKit Revealer showed some unknown hooks on the windows kernel that I'm still checking out. When I get a chance, I'll take some screen shots and display them. Meanwhile, I'm also checking on the UDF format compliancy, but this doesn't seem like the problem since I could read the DVD the first time and after that my drive shows this particular DVD is not there. -BP |

@Dialhot,
Rootkit Revealer (aka sysinternals) reported only one discrepency "HKLM\System|ControlSet001\Services\SPTD\Cfg size 0 access denied" This is a real mistery to me :?: I'm asking questions from my friend what exactly was done to create this DVD. Thanks -BP |
SPTD = Scsi Pass Through Direct.
It's a virtual drive daemon used by DaemonTool (but maybe others). http://www.daemon-tools.cc/dtcc/showthread.php?t=7687 |
