Sweet update ozok! What about adding support for mp3packer? Your GUI for that tool would be sweet. Found some bugs: - When skinning is disabled: When extracting audio, the encoding variables/controlles is not greyed out like with skinning enabled. - Could not extract 5.1 DTS from mkv. Later, after demuxing with TSmuxer, TAudio manages to convert it. Tried with different mkv's containing different .dts with different bitstreams. This was supported in previous version.
