VCD/XA files not reading

VCD/XA files not reading

[Grahame Jordan]

Hi,

I have a video cd that mounts OK and reads the smaller files, but when I
try to read the mpeg file (avseq01.dat) it fails.  There seems to be
support for XA in include/linux/cdrom.h but it's not working for me.  I
downloaded the same file to my HDD and it works fine.

Kernel 2.4.16
CDROM: Pioneer DVD-116


When using:
cp avseq01.dat /var/tmp
cp: reading `avseq01.dat': Input/output error


dmesg gives:

hdc: command error: status=0x51 { DriveReady SeekComplete Error }
hdc: command error: error=0x50
end_request: I/O error, dev 16:00 (hdc), sector 1920

XA sectors aren't supported by the base ISOfs code. The ioctl interface
lets you read these sectors and play videocd but you'll have to do the hard
work in user space.
