Why cant I play DVDs recorded on liteon 5001b on other players

I’m new to these fancy dvd recorders. Liteon 5001b cheap and cheerful and does the job but when you try and play recordings made on it on other DVD players the disks won’t play. Manual says disks recorded on 5001b should just play and you don’t need to finalize the disks and that feature is disabled anyway on 5001B. Any idea how to fix this?

Any help gratefully received! :slight_smile:

Tombola this is not the right place to ask this question, there is actually liteon forum just for 5001/5005 you would do better to go there. They have all the answers.
