After using ToK quite sucessfully for my DivX conversions i had heard that it had problems with the MA script so i followed a guide for using CQMatic and heard that it was a really good calculator.
I know Kwag is working on a shutdown feature for future releases of his excellent tool but i thought in the meantime ppl might be interested in a tool i found on DVD Digest.
I did a search on there for shutdown tools as i knew they had them as i used to get my DVD2DivX tools from their good site.
This tool is called 'Shutdown Counter' its a real simple tool and works with most M$ OS (I not sure about Windows 2000 though

).
Its a real simple tool what i do is wait until CQMatic works out the best CQ and once the final CQ is found and TMPGEnc begins its full encode i then start this small util.
Say your encode will take 6-8 hours i simple add an hour to the timer and it will shut down after the time is reached.
Enter it in this format: HH:MM:SS <-- Hours Mins Secs.
go to options and select Shutdown and hit go and off to bed u can go.
Try it and see what you think of it.
Get it
