Re: [Freevo-users] Strange DVD problems with mmpython

[Zeratul]

I have the same Finding Nemo DVD and the same problem.
From /var/log/messages:
Apr 18 19:56:44 video kernel: hda: command error: status=0x51 { 
DriveReady SeekComplete Error }

.. goes up all the way to sector 1684
later it gave
Apr 20 22:48:18 video kernel: hda: status error: status=0x50 {

Apr 20 22:48:18 video kernel: hda: status error: error=0x00

and the third or fourth time I inserted the disc (each time removing 
mmpython disc cache), it just worked.

Hi,

some people reported a strange problem: some DVDs are _sometimes_
shown as normal cds. My new Finding Nemo DVD has the same problem:
insert it, it's a cd and this error is cached forever :-(. But if I
remove the cache and try again, it's a DVD. If I insert a different
DVD and the strange DVD later and remove the cache, it's a cd again. 

This bug is somewhere in libdvdread. I tried to find it, ifoOpen fails
with a read error (also shown in /var/log/messages). I have no idea
why this happens only when the disc is new in the drive. I also found
out that lsdvd works for some reason. I compared the code -- no
differences at this point (in fact, it's only DVDOpen and ifoOpen). If
someone can find this bug, please send a patch to the list.
 

mplayer also ALLWAYS works fine, just like lsdvd.
Me too I'll compare the code and see if I can find something
As a quick solution and also for runtime users I made something which
is bad for the original mmpython design: I wrote a lsdvd wrapper for
mmpython. If you have problems with some discs, install lsdvd and get
mmpython from cvs.
 

Are you sure this fixes it ? Because I am using mmpython cvs since 
yesterday because I wanted the lsdvd output.
The problem is freevo's DVD folder keeps saying 'No Disc' and I cannot 
enter the folder . (Yes, I cleared the cache..)
