Trying to use MakeMKV

[Humbug]

Hi there
Trying to use MakeMKV but keep getting error!
What i am trying to do is basically i have a bluray iso file which i want to convert into a MKV so that i can put it on a external hard drive and then play it thru my tv which supports MKV files.
I add iso file to MakeMKV and get the following error:

It appears that you have on-the-fly decryption enabled.MakeMKV should process discs with most sophisticated protections without help of any 3rd party decryption software.In addition MakeMKV works faster and more reliable when it decrypts data by itself.It is highly recommended to disable such software and restart the application.
Do you want to continue (errors may follow)?
Any ideas on what I am doing wrong or what software needs disabling?
I am using Windows 7
Many thanks for all advice given.

Or is there another peice of software i can try preferably straight forward like MakeMKV.
Cheers

Have you anydvd installed and enabled? Then shut it down.

No haven't mate
Only thing like this is maybe the following:
Convertxto dvd 4
Creative Zen X-Fi video convertor
Fairstars mp3 recorder
Okoker All to Mp3 Convertor 5.1
And a couple of burners Nero 9 and Imgburn

But did you tried click continue? It might work fine anyway.


BUT your tv might not support mkvs that makemkv make. It might only support mkv with h264 (with a specific encoding profile) and aac audio for example, use then a shrinker like ripbot264 or bdrebuilder and convert to mkv.

No didn't try to continue.
I thought it might just say take hours on end to convert just to find it don't work.
Should i give it a try,if so how long would it take to say convert a iso to MKV.
The film i've got is 46gb!
Tv is new Samsung LED 3D tv and plays pretty much every MKV file i have thrown at it so far.
Should i try the other 2 mentioned in your last post?
Thanks
