System Requirements
To have the best MyCasting experience, your home computer on which you install Orb 2.0 needs the following:
- AMD Athlon 3200+ processor or equivalent, or Intel Pentium IV 2.4Ghz processor or equivalent (Note that a slower processor may cause excessive buffering, "stuttering", or "choppiness" when streaming TV or videos)
- 512MB of RAM
- 100MB available disk space
- Windows XP (Home or Professional) with Service Pack 2 or later, or Windows XP Media Center Edition (2004 or 2005). Orb is also compatible with Windows Vista and Mac OS X Intel 10.5 or later.
- Broadband Internet connection
Note: We recommend a minimum of 1GB of available disk space for writing media (recorded TV, video, audio and photo) files.

Note on software-based, non-MPEG2 TV tuners
At this time, most non-MPEG2 tuners (such as: ATI All-In-Wonder family of tuners; Hauppauge soft-PVR USB tuners; etc.) will work in Orb. However the implementation of this functionality is still in beta and therefore not supported. If you cannot make your non-MPEG2 tuner work in Orb, search Orb forum posts at forums.orb.com where issues related to this type of tuners are discussed, and basic setup tips are offered.
