After dubbing from HDD to DVD-R the data seems to be on the DVD but the title does not copy onto the DVD's title list so there is no option to pay the disc, and when press the pay button on the remote a message comes us to say "there is no title". Also, the manual finalise message does not come up when the disc is ejected. This has not happened before, so I am wondering if it's a mechanical problem. Can you suggest a solution?
