HTPC - need some help

Okay, i am playing with an idea to build a HTPC. My knowledge about hardware is rather poor. So i'd like to have some advice.
What i expect:
- 1080p
- watch TV via DVB-T
- Blurayplayer
- music, pics
- wake the HTPC via infrared
I have a gaming PC and both should use the same Soundsystem.

I've chosen following components:
1 x Intel Core i3-2125, 2x 3.30GHz, boxed (BX80623I32125)
1 x Corsair ValueSelect DIMM Kit 8GB PC3-10667U CL9-9-9-24 (DDR3-1333) (CMV8GX3M2A1333C9)
1 x ASRock H67M, H67 (B3) (dual PC3-10667U DDR3)
1 x Antec Fusion schwarz/silber, 430W ATX 2.0 (0761345-08738-4)
With this CPU i dont need any GPU, right?
Which Bluray-player can you recommend?

I'm running a pretty similar setup, i3 2120 and a Asus H8M67M PRO motherboard.
The onboard graphics are okay, it manages HD fine.

There is however an issue with the graphics driver - I built the machine, connected it to the TV via HDMI and it was fine. I then routed it through an AV amp and the machine would blue screen on start up. Go direct to the TV again and it was fine.
The blue screen concerned the graphics card driver, I was using the version off the CD that came with the motherboard, this was version 8.15.10.2405. Through a bit of searching I found other people had experienced blue screen issues with this motherboard when connected to various equipment via HDMI. The answer is to roll back the driver to 8.15.10.2219 (available on the Asus website).. its the only way to get it to work - even the newest drivers from Intel will cause the problem.

Its not an issue, but just be aware you may need the older driver if you do see an issue, the blue screen will mention igdkmd64.sys

I have to install drivers/software. So thank you for the information.

Edit: i had problems with playing hd-files first. But with lav-filters everything works fine.
