okay, thanks for trying!!
I'll have to give up.
I don't know what I could be doing wrong.

Since it works for you, but not me, then it must be either some issue with the server which runs VDR or my network.
VDR runs on a headless server running on an Intel Core2 DUO E8500 processor.
I haven't tried playing the recordings on an xbmc client on the server itself, I will try that soon (no monitor).
This server runs stock fedora 20, with manually compiled/installed VDR (2.0.6 and 2.1.6).
I have 3 linux fedora 20 (stock) clients running xbmc.
All have the same issue.
I have a raspberry PI B also running XBMC using OpenElec.
This client has the same issue.
All clients are on a simple local LAN.
All linux clients are on 1000mbps (wired).
The Raspberry PI is on 100mpbs (wired).
Is there more debugging I can turn on?
I haven't started to look at the code yet.
I'm not sure where to start.
But I'm not afraid to try.
I did have pulseaudio on the server running with the multicast RTP sender/receiver enabled.
I thought maybe the RTP was congesting the network.
Disabling has no effect.
But, since I can play the recordings on all clients using the filesystem, I don't think it's a network loading issue.

Given all this information I suspect the issue on the server side. If I added some debug logs to the vnsi plugin, would you try this to get more info?

I am traveling and can't add more logs before Friday. It seem to read data from the file. Next thing I would look at is network. Maybe the network has trouble transferring those 32k chunks. Can you look at the network using a sniffer like Wireshark?

If I play the recording on the same machine as the vdr server, the recordings plays just fine, even with the older version of vdr and xbmc.
Therefore, I think it's clear I have some network issue.
I've started using wireshark to help identify what might be wrong.
I am not a sophisticated user of wireshark nor an expert on how to debug tcp problems with wireshark.
But I am trying. Googling as much as I can to get the help I need.
On that same ftp site, there is a screenshot.png which shows a capture while the video is playing.
I have compared capturing while viewing live tv and playing these recordings.
At a high-level glance, the behavior looks very similiar.
All of the packets are in the 2 to 4K sized range.
I never see the full 32768 sized packet.
It appears the tcp ports are always different?
My server and clients are all stock fedora 20 installations.
I certainly don't do anything specific for tcp configuration.
Maybe I have hardware problems.
I will try minimizing my network connections.
Why would livetv, which works fine, be different than recordings?
