Permanent link MP3: Foobar 2000. Or libMAD   

My favorite music player is now Foobar 2000. Some extensions I like:
Other good choices:
Winamp is easier to use. Foobar has better quality out of the box ; unless one uses libMAD or Ffdshow. MAD is one of the best MPEG audio decoder, the only one having an error rate under 10-7 (neither Foobar nor Ffdshow are compared on this list unfortunately).

Permanent link 5.1 3D sound on headphones   

Windows - Ffdshow

In FFDShow audio properties, open the mixer properties, and switch on headphone output and HRTF.
Or: use NVidia Purevideo audio decoder or PowerDVD filters. Or buy a X-Fi soundcard which supports CSS3D-Heaphones.
Also other sound cards like Nforce and Realtek SoundMAX also have 3d sound emulation on headphones. Set your headphone configuration as 5.1 in Windows, and as headphones in the soundcard tools or drivers.

Linux - Mplayer

mplayer -channels 6 -af lavcresample=48000,hrtf

Permanent link Linux and videos   

Hardware acceleration on GeForce 6200/6600/6800/7300/7600/7800/7900

Create the file /usr/X11R6/lib/XVMCConfig and put int the following line: /usr/lib/ To see a video in mpeg2 format (dvd, .mpg or .ts file):
mplayer -vo xvmc -vc ffmpeg12mc file.mpg


xine --post unsharp:luma_matrix_width = 3, luma_matrix_height = 3, luma_amount =2.0, chroma_matrix_width = 3, chroma_matrix_height = 3, chroma_amount =2.0

Also see contextual menu/Video/Post-effect/Reaction.
Xine pros: graphical GUI, quite complete. Xine cons: cannot read DVDs which are CSS-protected.


mplayer -vf unsharp=l3x3:1.5:c3x3:1.5 Video.avi

It can read almost any videos. But it's command line-based, and GUI usually are quite poor.

Useful keys:

Use the following command line (change 420:236 for the desired resolution, and alter the bitrate for more quality, here 1536):
mencoder -forceidx \
			 -vf unsharp=l3x3:1.5:c3x3:1.5 \
			 -vf scale=420:236 \
