Hi,
in the MLD you can find all data (tv, music, photo, video) at /data/... All devices are mount to /mnt/... Your network share also. /data/tv (the VDR recordings dir) is a soft link to /mnt/data/tv. If your network share contains only VDR recordings, you can mount it to /mnt/data/tv. There for you must change the mount destination in the /etc/fstab. If you don't know how, please post yout /etc/fstab, than I will give change it for you.
