DVBStreamExplorer is now offering a free version of its stream analysis software, but based on the Web site information, it does not appear to match the flexibility and functionality of TSReader.
The developers of DVBStreamExplorer announced the release of Build 82 and the release of a Free Edition last week. It has some interesting features, and while the Web site screen shots only show DVB streams, ATSC is supported—the announcement said that the ATSC SI/PSIP parser was improved in Build 82.
All versions support MPEG-2/DVB/ATSC PSI/SI/PSIP scanning, but only the paid versions include a real-time transport stream monitor. It should work with Windows BDA compatible cards. Unlike TSReader, it appears not to support MPEG-2 GOP analysis, based on the screen shots on the DVBStreamExplorer screen shots page.
The user interface and data presentation also differ a bit from TSReader. Now that a free edition is available, it should attract more users. At current exchange rates, the standard version is quite a bit more expensive than TSReader Standard, while the professional DVBStreamExplorer is a bit less expensive than TSReader Professional. Rod Hewitt's TSReader is available in free, standard and professional versions and works with a wide variety of devices accepting a wide variety of transport streams through Ethernet ports, ASI adapters, satellite or TV tuners.
