Toshiba DVD Recorder freezes

Hi all.

Over recent weeks my 4 yr old Toshiba XS24 DVD recorder/player is playing up so much I'm about to chuck it out.

It will not record from TV, or should I say, it records a few minutes then the picture freezes and the display clock stops with it.

I have to do a hard reset to 'reboot' it.

When playing DVDs, it will play but when I stop it, I have to restart it again before another disc will work.

I've taken the top off and given it a blow out with compressed air but it wasn't that dusty anyway. I thought that it may have been an overheating problem but apparently not?

Does anyone have any suggestions or is it ready to go in the bin?

Thanks in advance
