LiteOn HD-A740GX Copy is'nt recognised by DVD Players

Hiya I have just bought a LiteOn HD-A740GX and tried to copy from the HDD to DVD RW but it is not recognised by my other DVD player or the DVD player on my LAPTOP. When I put the DVD into my LiteOn HD-A740GX it is fine, has anyone come across this before??

Is it a + or - DVD RW? DVD-RWs need finalizing but DVD+RWs don’t.

I use DVD+RWs on my 5055gdl+ (very similar) and can put them straight into my PC.

thanks,it was a - rw. I’ll give it a try again
