I pulled some clips off my TRIDVR-ELE16C NVR to my windows PC and I'm trying to use the stand alone player to convert them to avi. I'm using player version 2.11.5 and it reports my 56 second clip as resolution 928 x 480. When i right-click and choose convert to avi the flie does get converted but gets output to 4 files. Strangely the 4 output avi files seem to alternate between different resolutions: The first and third files are 704x480 and the second and fourth are 928x480. I also tried the stand alone file converter and got the same result. Any ideas on what would cause this and how to output to a single avi file? 

Here are the thumbnails of the output in Windows:

Thanks for your help!
