Marratech v6.1 Readme file

Marratech v6.1 is available for Windows, Linux and Mac OS X. Marratech v6.1 includes major changes to the voice and video code. Please read the release notes carefully.

• Marratech v6.1 should be able to co-exist with 6.0 users in the same meeting room.

• Marratech v6.1 includes the ability to remove echo and feedback. This requires more CPU and memory and may be turned off if you have a headset.

Marratech v6.1 will run under Mac OS X v10.3.9 but has undergone very limited testing and is therefore unsupported. There are a number of issues fixed in Mac OS X v10.4 Tiger that improve Marratech performance. No separate download required.

For the latest minimum requirements, please consult the support section at http://www.marratech.com/

The Marratech client software is free to download and use under the conditions set forth in the License found at http://www.marratech.com/eula/eula.html

• You may keep the 6.0, 5.1, 5.0, 4.1, 4.0 or 3.4 version installed on your system. However, we recommend uninstalling them to avoid any possible confusion.

• Application Sharing requires everyone to upgrade and use version 6.0 or higher.

Version 6.0 and 6.1 can coexist in the same meeting room and should not pose any problems.

  • PCI capture cards default to PAL: Partial fix by editing the marratech.properties file with a text editor and adding NTSC as standard
  • OSS audio no longer supported, ALSA sound support required

• Echo cancellation feature requires more CPU. If you have a headset, it is recommended that you set "Echo Cancellation Mode" to "Off" in the Preferences / audio tab. This will reduce unnecessary CPU load
• Lipsync is disabled until next release. Enabling lipsync requires delaying the audio. We feel this does not give a good user experience. We will improve H.264 performance further until next release and re-introduce this feature

• DV cameras are not supported on Linux and Windows. On Mac OS X, DV video cameras (i.e. non webcams) will work but Marratech recommends the iSight

• Marratech does not support UFS (Unix File System) under Mac OS X. Please use the default HFS+
