------------------
Without knowing more detail, here's one thing to consider.  11Mbps access points are theoretical at best.  If two people are downloading/streaming at the same time, you cut that in half.  If 11 are using bandwidth at the same time, you get 1Mbps each.  That's the major problem with wireless right now, especially for bandwidth intensive activities (such as video).

Hello LLTIers!

Since we are *still* experiencing problems streaming video over our
wireless network (and probably over wired, but unable to test that
yet!), I would like your help in determining what could be expected of
streamed files.

We have both Real and QT files (although the QT is served from the Real
server). Our Digital Media Services encoded these files and they both
play at a "standard" size. Our throughput is 1 Mbps (athough there are
11 Mbps access points all over the place!). No matter where we set the
preferences for Real, there are still skips and halts when playing the
video at double size (double because the size is necessary when showing
the video in class through ceiling-mounted Proxima projectors).

Am I expecting too much to see mouths and sound synchronized with next
to no skips during play (at double size). At the regular size it plays
with no problems.

Also, the files look much better in QT, but it appears that the plugin
doesn't allow one to double the video size. Does anyone know if there is
a way to change that without re-digitizing everything?

Thank you for your help! Beth
