<br>it's impossible to to real-time encoding of high-def streams with a<br>general-purpose processor. Those that make the application-specific<br>processors for high-def encoders are still able to sell them for a huge<br>
premium--and will probably try to make sure it stays that way until all<br>the broadcasters have purchased their equipment (i.e. they don't want to<br>price it such that consumers can afford the capability when broadcasters
<br>can/will/are being forced to buy even with prices extremely high).<br>Then, factor in the content producers lobbying to prevent your getting a<br>copy of anything digital and chances are it won't happen--at least not<br>
in a way that Linux users can enjoy.<br><br>Note, though, that you can buy yourself a $10000+ high-def encoding<br>system if you really want. As for me, though, I'll stick with my $165<br>pcHDTV HD-3000's and free OTA channels.
