Tag Mclaren DVD32R DVD player-require help.

I have a Tag Mclaren model DVD32 player this player has two problems:
1.won't play all zones dvd discs. A software upgrade may help on this but I'm not entirely sure??

2.The top automatic opening sliding door won't shut properly (sticking) Maybe silicon grease on the runners would help??

Is anyone familiar with servicing this un common brand of DVD player?
Thanks.
