Cyberhome 1600mu not consistent



I have a cyberhome 1600mu dvd recorder. Sometimes I can record a tv show from my Input 1 w/s video and it can be copied and edited with DVD Shrink.
It does seem that many times I cannot copy it with DVD Shrink. Is there a particular firmware for this unit that works better?
I would need help in identifying the firmware I currently have and then see if another version or setup would work more consistently.
Thank you ahead of time.
