<DIV>Subsequent testing with hyperthreading on and off (BIOS Setting) makes
minimal difference, other than changing the percentage values noted in
top!</DIV>
<DIV><BR>Silicon Dust's website suggests the 2.8 GHz Pentium 4 (or similar)
for HD playback is the minimum hardware specification. The test rig
seems to exceed that. Seems to me the solution likely also lies in
VDPAU, however for me even C4 does not play smoothly, I would have thought there
was enough grunt to manage C4, certainly SD MPEG2's of the same C4 content play
fine, so perhaps there are things they can address?? Problems also could
lie in the antennae strength (seems unlikely given other DVB-T gear is receiving
ok) VLC's ability to play, maybe the LAN or ? Given the
HDHomeRun is new to the NZ DVB-T market it would not surprise me if some
firmware upgrades prove to be necessary to get this working to the standard I
was expecting.</DIV>
<DIV> </DIV>
<DIV>Having sent Silicon Dust some debug info, they suggest there might be two
problems in my (or NZ?) system, it seems implied they think they can fix them,
something coming next week? Not sure about time frames but from what I
know of Silicon Dust I think we can expect fix(es) to be forthcoming.</DIV>
<DIV> </DIV>
<DIV>Seems when it is working to expectation that it is likely it would not be
too hard to create desktop icons linked to scripts that open a selected channel
from selected tuner, with variations on this theme. Also a web page with
buttons for opening channels / tuners would seem simple for someone so skilled.
With the market place being teased with the prospect of Linux phones I can
see other platforms taking advantage of such interfaces. Silicon Dust may
have been better to incorporate webserver centric graphic applications for
multi-OS uniformity, rather than doing separate OS apps. </DIV>
<DIV> </DIV>
<DIV>It will be interesting to see how this runs up with MythTV and whether this
experience is at all relevant in that environment.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>
<DIV>For Myth systems with multiple front ends and knowing how the mythtv
development focus is less liveTV focussed, this device also has the potential to
create a complimentary multiple location live HD TV alternative.</DIV>

<DIV>Would you be willing on doing a quick write up of using the hdhomerun
from the CLI that I can post at mythtv.co.nz. At the moment I've mostly used
the gui based tool rather than a pure command line approach for my own
review.</DIV>
