I was wondering if anyone has had any experience with the Darim M-Filter as it relates to creating vcds. I've heard various opinions on the quality of the video after it has been filtered. Will the M-Filter help produce a vcd which is mostly free of blocks? I would be using the M-Filter in conjunction with the PV231 encoder. I realize that vcds will always retain some blockiness. It would be nice to know if having the M-Filter is as good as not having it.
