Hardware:<br>
- core2 duo ~3GHz<br>
- 4G RAM<br>
- many 7200rpm HDDs, but with only two configured as
storage groups. drives are currently ntfs. This will
change in the next few days.<br>
- 2 HVR4000 tuners<br>
- Cheapo Nvidia card, (gt9500?), doubt that's relevant.<br>
<br>
I do have a motherboard with a core2 quad and 8G ram that
I'll probably stick in the backend this week. Maybe I
should just try that first?<br>

<div>You've got more than enough CPU and RAM for recording,
I doubt this will help unless there is something else
running on the box?<br>

I do use it as a PC too, so sometimes firefox is running. Firefox,
for me, is like having a bloody gorilla in your RAM. I had thought
(but not checked) that this would swap out when I wasn't around for
a while. Frontends on other machines report 3.9GB total, 3.7GB used,
138MB available. This is pretty consistent no matter what the
backend is up to, so I suspect a myth bug. gnome-system-monitor
reports about 900MB used at the moment. At the moment I'm not having
recording issues either...<br>

- it might be worse when there are multiple simultaneous
recordings<br>
- it comes and goes<br>
- might be worse when the backend has low ram<br>
- seems a bit better after rebooting the backend<br>
- not sure if it affects dvbs or just dvbt<br>
- i haven't done the math for required throughput for the
HDDs or the PCI bus.<br>

<div>If it's not consistently happening with simultaneous
recordings it's probably not a throughput issue. You could
try recording say 6 things at once to test this.</div>

I will try this.<br>

Can't think of anything. I'm about to move a bunch of data around
and get them formatted as ext4/xfs as appropriate. I will see how/if
this affects recordings in progress.<br>

Of course, this might be simply bad reception. I haven't
seen any correlation with terrestrial weather. Have not
looked at solar weather.<br>

<div>Bad reception would be my guess. Does it happen during
live TV?<br>
