[mythtv-users] Backend drops frames at start of recording; add RAM?

[kanetse@gmail.com]

I have noticed that when my master backend is starting to record 3
programs simultaneously, it tends to drop frames at the beginning of
the recordings.  By my estimate, it probably drop around 30s to 1min.
I have confirmed that it's not a frontend issue, because the
recordings always skip at the beginning, and regardless of which
remote frontend I use to view the show, the exact same frames are
skipped.

I think it has something to do with the 3 tuners being set to record,
and then stopping the recordings that were previously going, as well
as starting up and queuing all the new and old transcoding/commercial
flagging jobs.  I allow the machine to run 2 comm-flag/transcode jobs
simultaneously.

My machine only has 512MB RAM it (but it's a dedicated backend).
Would topping this machine up to 1GB help this problem?

My dedicated backend specs:

MythTV-0.19-127
1xPVR-250
1xPVR-500
512 MB RAM

Celeron D 2.93 GHz
Fedora Core 4



Thanks!
