How Can I Extract Unfinalized Videos From A Mini Dvd Created With A Sony Handycam

When I play this DVD in my PC it shows “Empty” but in “Nero” it shows size about 1.3 GB. So, I think my videos are alive on the DVD, but I am unable to read/see them.

Please someone tell me how can watch this DVD?

How can burn it to another DVD?

How can I finalize a Sony Handycam without a Sony Handycam?

Please help me!

Thanks in advance!
