Watching DVD movies on TV is fun, and you may like to burn movies to DVD using software on your PC. But, often the subtitles are missing in these burned DVDs. DVD burning software doesn’t provide an option to include subtitle files, that it will burn along with the movie. Also, you can’t drag and drop subtitles while playing a movie on your TV. Therefore, it is better to fix or attach subtitles to the movie file. That way, you don’t need a separate subtitle file, just play the movie, and the subtitles will appear on your TV or computer screen. This can be done with the help of third party tool.
This tool is known as AVI Recomp. It is free to download and supports AVI files only. You can add your own subtitles and adjust their common settings; such as position, size, color, font, outline, shadow, style etc. By using this tool, you can perform other tasks; such as recompressing (reencoding) AVI clips using Xvid codec, adjust all encoding parameters for better performance, audio conversion, batch encoding, etc. Here’s a step by step guide to attach the subtitle file on an AVI video.
Download and install the AVI Recomp tool  to your computer. The installer file is a bundle of three different types of software (Xvid, Vobsub, and AVI Recom) and they will be installed one by one.
Run the application. In the program interface, click on the Open AVI button to select the AVI file (movie or video file) from your PC. Now click on Save AVI to decide the output file location.
Click the Additions tab. Check the box next to Enable/Disable. Click on Load subtitles (.srt file) and select the subtitle of the video from the location where you saved it.
Go to the Queue tab. Click the Add to queue button to add your job. It will appear in the Job list box shown below.
Now click the Start button to start the process.
Minimize the program to your system tray.
Note: This tool takes several hours (2 to 3 hours or more) to complete the process. It sits in the system tray, therefore it’s a good idea to minimize it and find something else to do (this might be a good time to take a quick nap).
After it completes the process, check out the output video. When you play it, you’ll see a subtitle along with the video, no extra subtitle files needed. Now burn a disk and play it on your DVD player or enjoy it on your TV set.
