To build the DVB/V4L drivers from CVS, follow the directions at<br>

Make sure to also reboot after installing the kernel as they<br>
describe in step 2.<br>

I have the FusionHDTV5 Gold, but according to the mailing lists, the<br>
Lite works as well. I'm quite happy with my Gold. I'm currently only<br>
using it on cable, so I cannot comment on its OTA reception. Also, if<br>
you get the Dvico MCE remote (which is bundled with the gold), search<br>
the mythtv archives for a patch to lircd to make it work.<br>

<br>skips and artifacts. But if I use pid filtering to record JUST<br>DiscoveryHD or TNT-HD, then the stream is fine. Note that myth<br>does pid filtering, but there are plans afoot to allow for recording<br>multiple streams from the same dtv multiplex (which is basically like
<br>my example of recording all of channel 84). I would guess that that<br>lite would be worse than the gold for cable, but you never know.<br><br>Also, the gold I have requires a bit more signal than my TV's QAM<br>tuner does. The gold only started to work once I put an 8db amp
