Optibox Spider HD

I need a little help here… I have got an optibox spider hd which I have patched to get menu 7777 and menu 6666

I have placed an NEWCAMD line on and it clears the channel fine but after about 1 minute it start to freezes… do I need another patch? If so what do in need? Do I need to change any more stting on the box to stop it from freezing?

Thanks,
