Yes, I've seen this, and I'm working on it.  You should also be seeing
this kind of message in /var/log/messages:

  Nov  3 17:04:58 afa0001 kernel: cxm0: encoder dma not enough buffer space free

Try this patch:

--- /usr/ports/multimedia/pvr250/work/dev/cxm/cxm.h     Sat Dec  9 13:28:01 2006
+++ /usr/ports/multimedia/pvr250/work-in-progress/dev/cxm/cxm.h Thu Nov 30 18:30:15 2006

        enum cxm_byte_order byte_order;
 };

-#define CXM_SG_BUFFERS 50
+#define CXM_SG_BUFFERS 500

 struct cxm_buffer_pool {
        bus_dma_tag_t           dmat;

Then rebuild the module, unload the old module and install the new
one.  Please let me know how it goes, whether or not it works.  I'm
currently in the process of importing this driver into the source
tree, and this is one of the things I'm planning to make a tuneable.
