Can't play blu-rays on re-installed Win7

[bulb763]

Did a fresh install of Win 7 on my Acer laptop and have since been finding, downloading and installing all the drivers that I should have made a note of before hand.

Out of the box I was able to play blu-rays with it but I can't now. Do I need drivers for this too? I can't find any. Think the software I use was Cyberlink PowerDVD, but it looks like I have to pay if I want to download it now. There is nothing on Acers site.

Any ideas?

Tried the K-Lite codec pack? Can't recall if you need the likes of PowerDVD installed to run BluRay discs.

Never even heard of it! Will give it a go...

Won't VLC play Blu-ray?

I've tried VLC and it doesn't respond when I put the blu ray in (I've tried three different blu rays). When I try and tell it to play, it returns this:

Blu-Ray error:
Path doesn't appear to be a bluray
Your input can't be opened:
VLC is unable to open the MRL 'bluray:///E:/'. Check the log for details.

When I put the disc in, regardless of which player I want to use, there is no response from the drive. It doesn't try to spin the disc up, nothing. A DVD of the same film works fine. Before I re-installed windows it played blu-rays with no issues.

Might be relevant: I've done the fresh install because I've replaced the old HDD with an SSD and maxed out the memory.
ETA: also changed something in the BIOS to AHCI, because of the HDD > SSD swap.
