TSSniper Ver 0.80

I am able to load a file and I get the main window. I can select the cut points but when I click on the "Delete current selection......" button, nothing happens, although eventually the program will stop working. The video's are .ts files taken from UK terrestrial TV broadcasts.

What am I doing wrong?

I am using Windows Vista 32 on a Dell Laptop. Intel Duo T5750 CPU 2.00 GHz

This is what "Media Info" has to say re one of the sample files I am trying to cut.
