I saw this problem also a few times and every time I saw it I found an
entry in /var/log/messages:

linux vdr[2481]: ERROR (dvbdevice.c,547): Device or resource busy

=> so I assume that this is no dxr3-plugin problem but a VDR / driver 
problem.

OK, I think this problem is caused by a wrong detected audio header.
Just try the following patch:

*** dxr3audiodecoder.c_orig	Fri Apr 25 00:13:04 2003
--- dxr3audiodecoder.c	Thu May  1 11:05:36 2003
*************** void cDxr3AudioDecoder::Decode(const uin
*** 54,60 ****
      };

      int i = 0;
!     for (i = 0; i < length-4 && !foundHeader; i++) {
          unsigned int tempHead = *((unsigned int*)(buf+i));
          if (HeadCheck(tempHead)) {
              if ((buf[i+2] & 0xFC) != (lastHeader[2] & 0xFC)) {
--- 54,60 ----
      };

      int i = 0;
!     for (i = 0; i < length-4 && !foundHeader && pts; i++) {
          unsigned int tempHead = *((unsigned int*)(buf+i));
          if (HeadCheck(tempHead)) {
              if ((buf[i+2] & 0xFC) != (lastHeader[2] & 0xFC)) {



This should fix the sporadic audio problems as well.

Sorry, but I can't reproduce this problem. Cutting works for versions on my
system. I would need a sample stream to debug the problem but
unfortunately my internet bandwith is limited.
