is there a way i can copy vts files to ext hard drive so i can watch them on my dvd player thru the usb port on the dvd player
Use VOB2MPG to convert a ripped DVD movie Title to a single, large, mpeg2 file (assuming the player will accept them). The DVD player manual will tell you if the HDD has to be formatted Fat32 or NTFS. A Fat32 HDD (or flash drive) won't accept a file larger than 4GB, so depending on that restriction, you may have to use a program that can get the file down to the limit. Any external HDD or flash drive that I have seen is formatted Fat32 - but if the player will accept NTFS, they can be converted easily. The drive properties will show the type of file system.
