Re: [dvd::rip] Illegal division by zero

Jorn,
despite you may be angry against these Italians ;) ;) ;) can you pls let me know what I can do here ?
I am still experiencing this issue with ANY DVD I load in.
I look forward in getting good results from this build from scratch
Thanks !

I finally installed fresh DVD::rip 0.97.11 but still same issue when I try to rip ANY DVD I load into the dvd tray.
I get this on screen while ripping:

When I make "tcprobe -H 10 -i /dev/cdrom -T 1" I get this:

Whan I try to read the DVD TOC, I ALWaYS get this type of message:
    
Means "always" for every DVD you try or always for one specific DVD?

  
If I try to make "tcprobe -H 10 -i /dev/cdrom" (took from the logging) I 
get something like this:
*** libdvdread: CHECK_VALUE failed in ifo_read.c:597 ***

Obviously tcprobe resp. libdvdread have trouble with this DVD. Since 
tcprobe doesn't print anything useful (in particular the frame size), 
dvd::rip later runs into this "division by zero", when it tries to 
divide something through the frame height.

  
Any idea on how I can get rid of this issue ?
    
If it's specific for one DVD, probably nothing, because it's badly 
authored and libdvdread simply can't handle it.

You could try to upgrade dvd::rip to 0.97.11 - it uses another tool for
DVD probing. But if the DVD is seriously broken, this won't help much. 
Probably you'll get the TOC reading done, but later transcoding may 
crash. But it's worth a try.

Joern
