the last official version of clonedvd caused a problem on my pc. my burst rates on my dvd drives were lower and caused my burned dvd's to stutter. i went and bought almost an entirely new pc cause I assumed it was the motherboard malfunctioning. i put it together, installed windows, and all the usual programs I use. Same problem with the low burst rates. Someone suggested I run devfilter.exe and remove whatever 3rd party programs I have listed as the upper/lower filters. lower filter showed elaborate bytes. i uninstalled clonedvd and the problem went away with that. I kept every other program except for clonedvd. clonedvd was updated in january and my problems started 2 months ago. whatever you guys did in that updated caused me to waste $600 on new computer parts. thanks a lot! I used Clonedvd for three years without a problem on several different pc's until the last update. Now I use nero recode cause I edited. HATE CLONEDVD.
