Hi,

I tried the final driver yesterday and I was not able to get this error
again, but maybe I need some further tests, so don´t see this as a final
statement.
But: With this drivers, I have heavy artefacts on N-TV and VIVA 1. All
other free german channels (at least from the autopid-channels.conf)
made no problems. Using again the old drivers, there were no problems.
Maybe this has to do with the PCI latency, but the last drivers I tried
also worked with a PCI latency of 64 and AFAIK this is also the default
value of the new drivers. Additionally I think that if there was a
latency problem with the latest drivers more channels would be affected.
Going to check the new introduced 'latency' parameter this evening...

Any ideas or similar experiences with the new drivers?

Jörg
