i am using the dl version 1.05.
1st.
i cant use the seek bar if playing an hd avc mkv file
edit :
it works with some files but it wont work with others codec and container are always the same... is may depend on the index of the file if seek is available ore not.
2nd.
no manual aspect control is possible. some videos are wrong scaled
3rd.
i cant find a way to adjust brightness and contrast manual.
i hope your motion estimation type will be as good as the one wich is available via avisynth and ffdshow. i am watching your player now a long time and if the pro version can make it better faster and with an higer quality than ffdshow/avisynth you will have one customer.
and also i hope you know about the way avisynth and ffdshow is working this out.
