I use k9copy to backup the main title (without menu) of video DVDs. Since approximately 2 weeks it stopped working properly: While the time elapsed is displayed correctly, the total time soon drops to 0:0:0 (later counting some seconds) and percentage complete stays at about 3%. It does continue anyway, but the DVD structure created is corrupt: It is very small (1-2GB), has reduced running time and some chapters are shortened:
$ lsdvd -c /path/to/orig/
Title: 01, Length: 01:21:35.210 Chapters: 13, Cells: 13, Audio streams: 08, Subpictures: 32
Chapter: 01, Length: 00:10:26.000, Start Cell: 01
Chapter: 02, Length: 00:10:17.020, Start Cell: 02
Chapter: 03, Length: 00:10:10.330, Start Cell: 03
Chapter: 04, Length: 00:09:41.370, Start Cell: 04

Chapter: 05, Length: 00:01:39.280, Start Cell: 05Playing the copied structure with xine dvd://path/to/copy/ shows good quality in the first few minutes, but then it suddenly gets worse, showing large blocks like a video created at very, very low bitrate.
I tried 6 DVDs (each a different movie, not a series using some strange copy protection, as one might think) - same result. I created an okay 1:1 copy with dvdbackup, then ran k9copy on it - same result. As a workaround I am using dvdshrink/wine now, which worked without any problems so far (same 6 DVDs), but I'd really prefer to keep using k9copy, which never showed such behaviour before. My first assumption was that the problem was due to an update of kdebase-runtime, so I downgraded to 4.6.0-1 - same result. I also recompiled k9copy using ABS (tiny patch required) - same result. What else could I try?
Some k9copy settings (not changed lately):
DVD size: 4470 MB (or 9000 MB, if main title fits on single-sided DVD)
[x] use dvdAuthor for copy without menus
[ ] quick scan
DVD read ahead: default
[ ] Keep original menus

I do not know, but k9copy don't work for me too.
I'm using KDE4.6.1 and k9copy v2.3.6, using Arch without HAL.
DVD is correctly recognized. I select title for ripping, but after that nothing happened. (no ripping preview window)
Only message that job is done.
All dependencies and backends satisfied...

Thank you for your reply. I can confirm that k9copy may not work at all. I installed and tested it on two other computers, both running Arch Linux, one of them not updated for quite a while, the other up to date (but using the testing repo). On both of them k9copy immediately informs that the job is done, while the output directory VIDEO_TS is empty. Really strange, I didn't find the reason for that either.
I remember that k9copy had a tendency to just skip parts of the DVD whenever there is a read error, but this rarely happened, while now only one of numerous attempts created a copy that actually was complete. Choosing the option "skip bad sectors" didn't help. I also was thinking about HAL, which I removed two months ago, but this didn't have a negative effect for a month, if any.

I resolved this problem on my Arch.
Simply delete K9Copy config file from .kde4 directory:
rm ~/.kde4/share/config/K9Copy
and start K9Copy again.
It's work for me.

Deleting that file did not help in my case. K9copy then switches to default options, e.g. "Keep original menus", which I then disabled again. Meanwhile, I found out that the shortening of chapters is due to k9play crashing, which sometimes, but not always, brings up a dialog for reporting a bug. I recompiled libpng, k9copy and qt with debugging enabled as described here, but according to the dialog k9copy and qt still lack debugging capabilities, so I did not report a bug so far.
Today I focused on one DVD which I had copied 1:1 on hard disk using dvdbackup. I ran k9copy two times on that copy and both times the same five chapters were shortened, but at different positions. Now I selected only one single chapter of the main movie to be copied and started k9copy from a terminal to see the comand it executes.
/usr/bin/dvdauthor -x /path/to/output/k9aUV4453.xmlI made a backup of the k*.{xml,yuv,inj} files while k9copy was running and looked into the xml file, where each chapter is created separately by k9play:
<vob file="/usr/bin/k9play --play --input /path/to/input --dvdtitle 12 --chapter 1 --cell 1 --audiofilter 1,2 --subpicturefilter 1,2 --vampsfactor 1.00 --inputsize 361490432 --chaptersize 361490432 --initstatus --inject /path/to/output/k9vGz4453.inj --totalsize 361492480 --dvdsize 4613734400 |" chapters="0"/>When that command is executed manually the crash becomes visible
$ /usr/bin/k9play --play --input /path/to/input/ --dvdtitle 12 --chapter 1 --cell 1 --audiofilter 1,2 --subpicturefilter 1,2 --vampsfactor 1.00 --inputsize 361490432 --chaptersize 361490432 --initstatus --inject k9vGz4453.inj --totalsize 361492480 --dvdsize 4613734400 > out.mpg
