Whats New...

MMSSTV-YONIQ from Spain is available for download on the MMSSTV-YONIQ page. 

MMTTV is open source and because of this it was possible for this version to be made. In the beginning it was a problem for English user as the program was in Spanish only. This was changed in a newer release.

Note that when you run the install and first start the program it will be in Spanish. It can be changed to operate in English after the program is installed. English instructions for installing are now available.

Instruction for installing MMSSTV-YONIQ and changing it to English, with pictures, is now available on the MMSSTV-YONIQ page.

  • Work slowly continues (in the background) on website updates. You will notice some changes from time to time. 
  • Remember use the groups support page for MMTTY & MMSSTV.

Although all possible effort has been put into testing and check this install process, I except no responsibility for problem that may occur and/or cause undesirable results from using the installer.

In simple terms:
Everything worked fine when tested but computers being what they are one can never know what things can happen. It is very unlikely that you will experience any problems but occasionally things go wrong..
