Handbrake hangs at 100%

I wanted to convert one of my exercise DVD discs (VIDEO_TS folder) to mp4 but for some reason, Handbrakes always hung at 100% and the file kept growing. The activity window showed the following:

[14:12:47] sync: adding 252 ms of silence to audio 0 start 15879500, next 15856782
[14:12:47] sync: adding 307 ms of silence to audio 0 start 16039772, next 16012100
[14:12:47] sync: audio 0 time went backwards 0 ms, dropped 25 frames (next 16040900, current 16040900)
[14:12:53] sync: adding 70 ms of silence to audio 0 start 19398884, next 19392572
[14:12:58] sync: adding 70 ms of silence to audio 0 start 22515044, next 22508732
[14:13:03] sync: adding 70 ms of silence to audio 0 start 25631204, next 25624892

After using Ctrl+C to kill the process, the resulting file only has the first two chapters, the rest of it consisted the repeats of a couple of frames.

I used Magic DVD copier to cut down the DVD content to only the title with the chapters I want. But Handbrake still hung at 100%.

Finally I concatenated the VOBs (there are three, copy /b file1+file2+file3 big_file) in the folder and converted it. Finally, it was a success.

Looks like the problem is something to do with the wrong Chaptering and sync. Handbrake just couldn't handle it. And it can do it if it's pure vob files. Still a mystery to me...

TDSS Toolkit Infection Fix

Finally I got rid of this crazy Google search result redirecting virus. I'm pretty certain that I got it (and others which are easier to remove) from one of free games for Nokia phone sites. I struggled with it for more than a week. What a shame. This really taught me a huge lesson about nothing is free...

Symptoms:
1. Fake Windows XP Security Center showed up and it said I should turn on some security thing.

2. Some kind of virus doctor window showed up and started scanning.

3. Task Manager button was grayed out when Alt+Ctrl+Del were pressed.

4. regedit, regedt32 were disabled.

5. Windows update site was blocked.

6. Google search results got redirected.

7. Tab completion is disabled in command line.

8. Does not recognize .exe file

Fix:
1. Download ComboFix from bleepingcomputer and run it. This program takes a long time to run but it's worth it.

2. Download TDSSKiller.zip from kaspersky and run it. If TDSSKiller says your atapi.sys or tskXX.tmp (XX is a number, it's different for each system. Mine is tsk21.tmp) is infected and wants you to reboot to fix it. Don't do it yet.

3. If the problem is with atapi.sys, find a clean XP machine with the same SP level, copy its atapi.sys in c:\windows\system32\drivers to a floppy or flash drive. Boot the infected system to Safe Mode (F8 during system startup) with Networking, replace the infected atapi.sys with the clean one. Do step 4 although TDSSKiller doesn't report tskXX.tmp is infected.

4. If tskXX.tmp is infected, run regedit (To re-enable it if it's disabled by virus, run
gpedit.msc->User configuration -> Administrative Templates -> System.
Choose "Prevent access to registry editing", set it to disable and then set it back to Not Configured.). Search the specific tskXX.tmp in the registry and replace it with atapi.sys.

5. Delete tskXX.tmp in C:\windows\system32\drivers

6. Reboot

7. Clean up and prevention

a. Re-enable Alt+Ctrl+Del: Run gpedit.msc->User Configuration->Administrative Templates-> System->Ctrl+Alt+Del Options. Choose "Remove Task Manger", set it to disable and then set it back to Not Configured.

b. If you're using Firefox, I suggest installing the following Add-Ons to prevent future infections.

NoScript
Verify Redirect

Hope this fixes your problem. It was such a painful process to figure this out...
