Yep.. i've also emailed Plextor and requested a few functions.. like for instance to be able to configure a CUSTOM LAME setting (like --alt-preset extreme, that i use).. as of now, you can only use standard VBR settings and you cannot change to Joint Stereo, etc.. It also needs ogg, mpc and ape ++ support.. but thats not the most important to me (and probably not Plextor either), since the majority of people use MP3 as their format.
Also i requested that PlexTools should queue encodings like EAC does it, so you can rip at full speed (for example if your gonna rip 5 cd's), and just wait for the encoding to be finished in the background.
Got a positive reply from them about it, so let's hope they listen to their customers
