Tvheadend

Hi,

I keep struggling to get good recordings with tvheadend. I use DVB-T in the Netherlands (Digitenne) on my ship. I replaced the old antenna with a new one, a Glomex Panorama. For now I only have one PCI DVB-T adapter in my computer which is identified by tvheadend as a "Philips TDA10046H DVB-T". When I start to record I got a lot of these errors in de logging console of tvheadend:

When I watch the recording the sound is gone every now and then for a short time. And the image is sometimes disturbed. I also used femon -H to monitor the signal quality when recording. I guess the first line is when the recording starts and tvheadend changes the frequency on the adapter. The other lines are made during the first few seconds of the recording. I already similar lines as above in the tvheadend logging console.

As far as I understand the femon output is good, there are no uncorrectable errors and the signal has a reasonable strength. The system shouldn't be a issue. The recordings are written to the samsung disk which is formatted with brtfs. I want to replace the philips card with two TerraTec PCIe cards (both dual tuner), because the system has only 1 PCI slot. I also tried to records with an Haupage card and an external USB stick but they have the same problems. Any ideas how to fix this issue?
