[vlc] Problem streaming HD (.ts) file

Wed Aug 18 23:26:48 CEST 2004

Hi,

When I stream a high-def MPG file (.ts format) over UDP, the playback
is quite jerky.

The two PCs are running WinXP and are connected via a 
100Mbps Ethernet switch. Both PCs are running vlc 0.7.2.

I have configured vlc according to the instructions
in the VLC Windows FAQ 
(http://wiki.videolan.org/tiki-index.php?page=VLC%20Windows%20FAQ)

The message log says:
