Purchased this machine some years ago, and it’s given pretty good service, (apart from having to change the hard disc once) although I’ve rarely used the dubbing facility. Tried to today, only to be told I’ve inserted a ‘non-recordable disc’. (Same make as I’ve used before, purchased with the machine). So I tried a couple of others with the same result. Any suggestions, please? Another problem that’s recently occurred is the remote is only partially working – for example, I can change from SP to LP etc, but can’t change the input from AV1 – 2 etc. (but can on the machine)
