Everything seems to be working - it records, plays back,
does everything OK - except that sometimes the box
reboots itself?!<br>
<br>
There doesn't seem to be any particular trigger that I
can work out - last night it crashed while recording as
soon as I stopped watching something. It also looks like
it crashed overnight while recording, but not playing
anything. Of course it's also been up for sometimes two
days without a hitch.<br>

So ... more than six months later, I can finally revel the
culprit was ... THE C-P-U !!! <shocked gasp from the
crowd /><br>

<div>Nope, not repairable. </div>

<div>While you may have a bad CPU, it could be something
else altogether. You might not have had good thermal
conductivity with the heatsink, may not have had a good
seat in the socket, may have outdated firmware.
Additionally, you might be able to get away
with under-clocking, disabling a core, increasing
voltages, etc. Finally, I have seen similar issues caused
by a power supply, or the motherboard's power circuits/.</div>

<div>While the two chips you compared are similar in many
ways... they may be very different in terms of the demands
they place on other components in the system... in order
to have any assurance that it's the CPU, you would need to
do an apples to apples comparison and replace it with an
identical CPU.</div>

For the most part: true!<br>
<br>
But I also replaced the motherboard (I had an identical spare) which
involved re-seating the CPU, and re-thermal-pasting<br>
Also I recorded the thermals, it was all nominal.<br>
<br>
The big problem is I was tired of dicking-around with it, and wanted
it to Just Work (TM). Now it does :D<br>
<br>
You don't realise how much you depend on MythTV working. <br>
Ok so the kids wont go hungry if it doesn't perform, but it makes
life just that little bit nicer.<br>
<br>
thanks for the suggestions,<br>
