Any way to show callrecords

As far as I know, court needs original recorded device as well.

I am in the same situation and waiting to see whether court will accept my recording that has abuses.

You can still submit as proof, and then the forencic lab must endorce them as original and genuine. This is because you lost your original device.

I'm also going to submit these as proofs, but at a later stage.

I have just started my DV filed by my wife

Amaresh, You should submit the CD. There is no need to mention about the original device lost etc.

Let the other party deny the authenticity then comes forensic test etc. The other party has to prove that the Voice recording is fake so relax. 

Remember if you are genuine you need to be CONFIDENT.
