I think these is what you are looking for. If not let me know:
In terms of CODECs that you can use for largest audiences. The Flash Format has the greatest possiblity for viewership because 98% of web browsers can display flash streaming videos. If you want to use Flash streaming, you can look at doing compression using the Sorenson Spark CODEC that comes with Sorenson Squeeze Compression Suite. Also use Fraunhofer MP3 for audio.
If you want to use QuickTime you can use the MPEG4 Codec or Sorenson Video 3 codec for video and MPEG4 Audio, or Qaulcomm (for voice content) and QDesign (for music) and lately I use Fraunhofer MP3 for Music content. Both the MPEG4 and Sorenson Video 3 CODECS have a great install base. I must note that this MPEG4 CODEC is MPEG4 Part 2 not to b e confused with MPEG4 Part 10 which is H.264/AVC. Sorenson Video 3 CODEC for QuickTime has more of an install base because it came out in QuickTime 5. MPEG4 came in QuickTime 6.
For Real Media Content you can use RealVideo 10 CODEC for Video and RealAudio COOK CODEC for audio.
For Windows Streaming use WMV 9 Standard for Video and WMV9 Standard for Audio.
Many folks have that latest versions of Windows Media and Real because many sites have require viewers to update to the latest version of these players.
In terms of compatibility and best formats to go with for greatest viewership. I would set my priorities in this order:
#2 Windows Media
#3 QuickTime (These movies can also play in the Real Media Player)
#4 Real Media
If I find a better comprehensive resource that explains the different CODEC's for the different formats, I'll post it on-line here.
