Hi, Sorry for my bad english. I come from hk

I have read the 5.1 model "hts8562/98". Wanner ask some questions before buy it.
But cant find the specific section in the forum~

1) This model is HDMI decode dts.hd?
Because i have other electronic items such as Playstation3, old dvd player.
I wanner connect them as followings:
PS3 -> HDMI-> HTS8562->HDMI-> TV
Is it able to output dts.hd if the disc support?

2) is it support play movies or photos from USB Harddisk?

3) is it support RMVB format?

4) My wifi router need check of mac address.
is it able to check the mac address of the "hts8562"?

Thanks a lot~
