100 MBit wired is much faster an you get less errors than with 54 MBit
wlan.

Do you use NFS over TCP/IP?

I have a 2.4.21 kernel on the client and 2.4.19 on server.

I also use the madwifi driver on the client. The server is connected to
a NETGear 108 MBit access point.

A throughput of 1200 KB/s should be enough if buffering works right. And
if I specify a 8 MB buffer this covers more than 10 s of playback.

Why does vdr not fill up its input buffer?
