[mythtv-users] A few 0.19 and RAM questions

[Yeechang Lee]

Like all other 0.18.1 users on the list I am eagerly looking forward
to 0.19 (specifically, the ATrpms version). A few questions in
advance:

a) Is the (takes a deep breath) "Certain recordings on playback
   consistently crash mythfrontend immediately and/or prevent the OSD
   from appearing and/or crash the frontend when the OSD appears for
   any reason, although the recordings play back fine in mplayer and
   in the preview window" issue definitely fixed in 0.19?  I seem to
   recall reading as much, but am not sure.
b) Based on some hints I've read here and elsewhere I get the
   impression that many or all of the root architectural causes that
   result in IOBOUND error messages when recording HDTV (especially
   more than one at a time, or when there is other disk activity going
   on, including deletes and commflagging) are solved in 0.19. True?
c) What does MythTV use additional RAM for, if anything? I have 512MB
   on my frontend/backend that is solely dedicated to MythTV. Despite
   my best efforts at cutting back on extraneous applications and
   daemons, including switching from full-blown KDE to ratpoison and
   from xterm to rxvt, the system consistently uses 150-300MB of swap
   according to 'free -m'. If I were to upgrade to 2GB of RAM, would
   mythbackend automatically use the extra RAM to, say, buffer
   recordings so as to minimize the IOBOUND errors I mention in b)? Or
   would upgrading to 1GB, thus theoretically eliminating the need for
   any swap, be sufficient?
