start:
At this moment I do not have openelec running,
but to find  file on mounted partitions, proceed as follows
open a terminal, and type
 updatedb
wait untill that is finnished (takes a while)

then type
 locate MyVideoNav.xml

If it is on any mounted partition it should report the full pathfilename.

If not on any mounted partition, you can see partitions by typing
 fdisk /dev/mmcblk0
  then type p
when finished control C exits, WARNINg do not type anything else....

Example:
# fdisk /dev/mmcblk0
Command (m for help): p
Disk /dev/mmcblk0: 15.8 GB, 15811477504 bytes
4 heads, 16 sectors/track, 482528 cylinders, total 30881792 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00014d34
        Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1            8192      122879       57344    c  W95 FAT32 (LBA)
/dev/mmcblk0p2          122880    30881791    15379456   83  Linux


So 2 parrtitions here.
If there is an other one, say /dev/mmcblk0p3, then mount it
mkdir /mnt/something
mount /dev/mmcblk0p3 /mnt/something
then repeat the previous updatedb etc from the point 'start:' as described
above.

If that does not find your file it may not exist?
