They have a deal with Hisense and Toshiba so far. Anyone know of other. They don't have to pay themselves so they could use this dual monopoly to drive market share. Expect a very inexpensive 5th gen receiver LG announcement with advanced codecs by mid 2005. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
