- WMV/VC1, AC3, AAC, DTS, RealVideo40 decoding in the LGPL code, (VC1 is 
getting there)
- DivX encoding using the DivX encoder,
- MP3Surround encoding, keeping all channels (no downmixing),
- DirectShow capture,
- Seeking by bytes in AVISynth scripts,
- Internal file concatenation.

That's all I can think about for the moment.
