The video archives from the broadcast are available below. We also recommend you visit Codec Central to see a good test of clips in all three formats. Our survey received 13 responses, summarized below. The overall winner both for client software and broadcast quality was RealNetworks. User comments are at the bottom.
Several comments cite problems with audio volume and clarity on Windows Media.
All three encoding machines were fed the same audio signal. Real and Quicktime encoding software include audio level metering in their interface. However, the Windows encoding utility does not, and as a result audio levels were not set properly. Some sound cards provide software that displays input level meters, but we didn't have that available on our test machine. Thanks to everyone who participated.
