Hi Yatti,
The key to use CQMatic is to allways reset your TMPGEnc project otherwise TMPGEnc will fail.
And that's surely why you're getting CQ=89,xx.
Also make sure you save your tmpgenc project as a
text file.
The rest is more or less like using tmpgenc as without CQMatic.
I also think (as Phil does) that you'dd better start with CQMatic&TMPGEnc instead of going directly towards something like MencodeMe or PackShot using MEncoder.
You see, MEncoder is still in the early stages and MencodeMe or PackShot are basically GUIs to use MEncoder.
And we're still trying to understand "the beast"
Post if you run into problems with CQMatic again.
Cheers
