I have a similar setup, just with 100M ethernet instead of wifi and NFS instead of samba. wifi could be a problem, but if you're able to watch the same channel live you should also be able to view a recording.
Takes a lot more bandwidth to record & playback then just to record so the fact that live tv is fine doesn't amount to much I don't think.
I was referring to playing a finished recording and playing a file that is currently being extended by the "server" vdr -- alexw said that doesn't work well for him. It should, unless the disk and/or fs can't handle the two data streams concurrently, while keeping the latency low enough. I'm assuming the vdr server in powerful enough to handle the load, yes.

Hi,
My setup is a little bit more complicated as it is using a share drive on both machine. The two local disks are only CF. The file server is compose of 4x SATA II 500GB in raid 5 (total ~1.5 TB available) piloted by a promise controller and a fully idle 3 GHz P4 CPU. The throughput or the sustained write/read access is not a bottleneck. Here is a quick ASCII art drawing:
/-- 100M --[AP]~ WIFI 54Mb ~[vdr client/FF]-[TV]
[switch]--- 100M ---[CIFS/fileserver]
-- 100M -- [vdr server/B2C2]-DVB-S+DVB-T
This evening I will test the provided patch.
Rgds,
Alex

Using the patch provided by Artur, playing a finished/ongoing recording is smoother than before. Sometimes the player stops in the middle of a recording due to a zero size request. Here is the log:

As you can see the requested size is increasing until it reaches the max buf. This is also a period with freezes in the video (late delivery).
