Hello,

still using the latest CVS drivers and vdr0.80pre6 on Kernel 2.4.3. 
I don't know if its only my system or not: After some time recording the following happens:

May 24 21:34:43 catx04 kernel: dmxdev: buffer overflow
May 24 21:34:43 catx04 vdr[2718]: ERROR (dvbapi.c,746): Unbekannter Fehler 769
May 24 21:34:48 catx04 kernel: dmxdev: buffer overflow

Additionally, the ringbuffer usage is rising to 100% and the recording stops.

I did a minor modification at ringbuffer.c to see the bufferusage in early stages:

        if (fill > maxFill) {
           maxFill = fill;
           int percent = maxFill * 100 / (size - 1);
           if (percent > 0) // <--- set to zero
              dsyslog(LOG_INFO, "buffer usage: %d%%", percent);
           }
 
With this, i saw that the usage is always rising, never falling. It goes to est. 60-65% then stays there. After that the 
error as described abovepops up in system-log, then the bufferusage goes to 100%.

I use a celeron 466 and a 80Gig Maxtor HDD - this should be fast enough to write the data in time???
