The 35.2kb subtitle is a .srt file. As Claire said, you can open it in Notepad to see if it looks good, or get the free Subtitle Workshop from Uroworks software (v.2.51, not the v.4 beta) and open it in Workshop and check it out. However, if it plays fine with the movie in WMP then it should be OK.
The 1.59mb file you extracted from the rar is definitely not a .srt subtitle. If it is a subtitle it's likely an ssa or ass subtitle or part of a sub/idx subtitle pair. ConvertX works best with .srt subtitles, so you should stick with the .srt file.
Also, if you can see the file extension of the movie.avi file and movie.srt file but can't see a file extension for the 1.59mb file you extracted from the rar file then there would seem to be something wrong with it.
Why ConvertX doesn't load the .srt subtitle just because there's a rar file in the folder is something I can't explain. If I were you I'd just put the .avi and .srt in a separate folder and load from there.
Also, have you read the text document? Perhaps it will tell you exactly what's supposed to be in the rar file.

Are you saying that the extension of the video is .xvid-yyddr? If so, try renaming the exension to just .xvid or even .avi and see if it plays.
