What is the .GTS file extension? It’s at the end of the file name for movies that I have recorded on my satellite receiver Personal Video Recorder (PVR). It plays through the same USB slot of the receiver on the TV, but my computer doesn’t recognize it. Can you help?
The GTS File Extension
Apparently the GTS file extension is an extension used by CaptiveWorks satellite receivers. The CaptiveWorks Web site didn’t have a support section, nor did they have an area where you can download user’s manuals. However, I did find a little bit of information about GTS files elsewhere on the Web. These files are a variation of the MPEG video format.
Renaming the File
Some users have reported success by simply renaming the file with the .MPG or .MPEG file extension. Once renamed, your standard media player should be able to open the file and play it. To rename a file extension, right-click the file, choose Rename, and change the .GTS extension to either .MPG or .MPEG. Once renamed, try opening the file in Windows Media Player or one of your other favorite media players.
Alternative Media Players
Users have reported quite a few different media players that will play GTS files without having to rename or convert them first. Among the players mentioned are:
Try downloading one of these players and opening the GTS file directly from within the newly downloaded media player.
Using Software
If renaming the file extension doesn’t give you the desired results and none of the above media players do the trick, you can try editing software. You’ll import the GTS file into the video editor where you can then view, edit, or burn it. You may even be able to save the file as a different file extension such as .AVI or MPEG.
You might have decent luck with VideoReDo TV Suite. This is a product designed for editing your PVR recordings, such as from TIVO units and other PVRs, and burning the final product to DVD. While it may be overkill for simply viewing the file, it might work. Try the free trial version and see if you can view the GTS file. The documentation on the VideoReDo site didn’t specifically mention GTS files by name but it did say, “. . . works with the widest variety of PVR and DVR formats.”
MPEG Streamclip Video Converter is another option for converting the GTS file to a more universally supported file format. This product has versions for Windows and Macintosh users.
Hopefully, one of these options will work out for you. I’d first try renaming the file extension and see if you can play it in your favorite media player. If not, I’d download the GOM Player. Apparently the GOM Player actively seeks out video codecs, so it may prove useful in the future. Let us know if any of these solutions work as this file extension is relatively new and not much information is available yet.

A number of issues could be the cause of this problem. Let’s go through a few of them and see if any of them relate to your situation.
