I need some SIMPLE advice and instructions



Ok folks,
I have now begun to get the death throes of my second dvd drive on a 5027HC+. I was lucky enough to get a replacement drive out of a used machine that replaced my original (?) drive but it’s developing the same symptoms as the first.
So, here’s the parameters… I can understand the hands-on technology necessary to actually replace the drive, but reading all the numbers and brands on this forum has glazed my eyes over…
I live in the UK,
The drive needs to play as wide a variety of file formats as possible.
It must be easy to firmware upgrade from a mac (osx).
It must be as cheap as possible - (don’t want much, do I?)
I don’t mind replacing these things every coupla years or so… but every six months is a bit OTT.

So, can someone give me just one or two choices, and the best place t get them. I would greatly appreciate the input, but if you give me too many choices then I’ll just stare into the headlights.

thanks for the help
