I use pdf4free.exe n dopdf bc they are small n fast. attached.
The links above are the freeware vitual printer drivers that allow Windows user create PDF file via printing. Pick any you like. they are all similar in functionality.
Basically, all you need is to load the text file into MSword or similar editor, format it following TTV suggestion, download sample here

then print the file.
It is recommended that
1-you should make one chapter one PDF file, it would be faster to load with your PDF reader thus.
2- you should not use too many fonts in same file. Preferably, 1 font for TTV, title, n dich giã, biên tập in diff size; 1 font for the whole chapter txt. reason is PDF is embedded font file. the more fonts used, the bigger is the file hence slower loading.
3- you should not use too many colors in file. simple back white is the best.
4- chose standard font size 12DPI. considering many readers of TTV are not very young. they might not appreciate the small font size.
5- dont bother with image txt, watermark or password protection. TTV provide txt files for free.
Note
So far, there isnt a standard format for TTV PDF, why not proposing yours. the idea is nice n simple.
