This file in the original
Twinhan software package is the file that has all of the satellites and transponders to scan. Unfortunately, it is write protected so you can't use the editor in the software. If you want an updated satellite.dll file you can download it from DVBOwners.com. Renrua is the poster of that file. They list Twinhan lists the file on their download but it doesn't download.
I use ProgDVB 5.15.01 with my Twinhan card. It is also available with DVB-S2. I tried the others but had too much trouble.
Don't understand why you are using TSReader. Seems to be confusing your Twinhan issues.
