help with the market

hi,

I am new to android and need some help.
I just bought a zepad zenithink 180 android 2.2 1GHz 4GO

My market is working well, but i cannot get every applications.
The best ones, like: real player, netflix, need for speed, dead space 2 etc are not found when i look for them. The market also seems quiet empty, to me. Not very much apps in it. Is that a recurent problem?
My seller says, some apps are limited by android 2.2 but i cannot even get to them !!!

Please some help. was i wrong buying this tablet?
is my market (very) limited?

 

Thanks a lot ! I did this and now i could download Netflix, realplayer and others. i don't know what it did, but it worked. thx.
...
But i still can't download any need for speed or dead space. is that normal ? Maybe they are not in the market for the tablets.

 

Hi,
What do you mean by that, please?
I tried to download them from the market but there is some restriction for zenithink 180 , that is not a "market approved" tablet. How can i download them, so?
