I have recently purchased the Panasonic DMR ES10 recorder. It works fine, but i have a small problem. After i have recorded a program onto a DVD-RW it plays back fine on my machine, but doesn't work on any other machine. If you finalize the disc first, it will play on other players, but you can't then record on it again. Is there anything i should do on the recorder that could change this, or is it possibly the type of disc? I am using a cheap brand of DVD-RW (Mr DVD). Thanks in advance. Chris.
