Hello bamoffthelip,
Thank you for your post and please excuse for possible inconveniences.
Actually, this is the wrong behaviour of AVI Trimmer, it should not let you save the output file with the same name as the input into one folder.
Do you use the latest version from AVI Trimmer + MKV's home page (2.0.1204.27)?
We have not reproduced the crash, but there are really some problems if the user would like to save the output to the same folder as input and under the same name.
So, if you use the latest version, could you please upload the original file for we could reproduce the crash also?
You can use any file host service, e.g.
filedropper.com or
dropbox.com.
Thank you in advance.
