The files are recorded with PVR-250 then transcoded to MPEG-4.  I
also have some recorded with a bttv card straight to MPEG-4.  I'm
using dsmyth v.61.

I can't recall exactly, I'll check tonight.  It was definitely the
norm, however I remember a few files that could seek, but then lost 
all sound when you did.

I've updated my mythtv to cvs since the protocol change I believe
so I won't be able to attempt to connect to the backend.

My backend is actually connected to my network with an 11g pci card.  My
desktop is then attached to the wireless router with 100Mbps ethernet and
was able to play off samba shares on the backend fairly well, but with 
some jumpyness.  Connected via the backend it was very smooth, however 
the interlacing was very annoying.  The laptop has built-in 11g and seems
to have some problem connecting to the backend for some reason - it just 
sits there until I stop it.  Playing files from the samba share is very 
jumpy, worse than on the desktop. Of course the laptop has half of the 
bandwidth that the desktop has since the wireless network is in 
infrastruture mode.  Somehow I got it to connect to the backend once and
only once and it played beautifully smooth though still with the interlace
issues.  But I never got it to do it again and think that the problem must
be with the laptop connecting to the linux machine.  When I connect to the
samba share from windows I get an error that it isn't available, and then 
it shows the directory, so I think something may be setup wrong, but the 
mysql lookup doesn't seem to have any problems.

I looked at the DScaler project a few months ago and unfortunately
it doesn't look like the directshow filters have been worked on for
a couple of years in cvs.  Do you have any different information
on it?
