Hi Tony,<div><br></div><div>I am using the latest .25 version. My storage group setup at the moment is just the default as i have been testing with other software and reinstalled mythbuntu recently. I have tried with 2 storage groups though, one on local hdd and the other on NAS balanced by I/O.</div>
<div><br></div><div>According to mythweb status the system load average seems to be quite high (like 10) when recording many streams. But on a recent test everything worked well. However I'm sure there will be problems down the line as I have another PC setup with windows software with the same hardware and it encounters problems also when recordng many streams.</div>

Hi David<br>
<br>
It would help if you let us know which version of myth you're using<br>
and a bit more detail about your storage group setup.<br>
<br>
Just to let you know I have a setup with 4 physical and 12 virtual<br>
DVB-T tuners and 3 physical and 6 virtual DVB-S tuners. I run .23<br>
fixes and have my storage group spread up over 3 drives (fast Seagate<br>
Constellation 2 drives not in raid or anything). I have for test<br>
purposes recorded 18 streams of which 6 were HD simultaneously for an<br>
hour without problems.<br>
<br>
It sounds to me though that you're doing this for a commercial<br>
operation? If so how important is 100% deliverable?<br>
<br>
Regards<br>
<br>
Tony<br>
