That is normal behaviour...
In my script I repeat the setchannel command 3 times or so... :-))
And I never missed a show due to that problem since then (taken from "A Few
Good Men")...
        pvr250-setchannel -g 352x576 -a on -t -m 4 $3
        sleep 2
        pvr250-setchannel -g 352x576 -a on -t -m 4 $3
        sleep 2
        pvr250-setchannel -g 352x576 -a on -t -m 4 $3
        sleep 2
        pvr250-setchannel -g 352x576 -a on -t -m 4 $3

I did that the first time on my very old fax-dsl-ntp-pvr-server and had similar
problems...
I do not know how it comes but I have no stability problems (uptimes over 40
days with about 4hrs pvr recording every day) since I use very high block
sizes...

Try
  dd if=/dev/cxm0 of=/tmp/bla ibs=1m
Or
  dd if=/dev/cxm0 of=/tmp/bla bs=1m
???

I wrote a little C program, that does this quite nicely even over a network
without crashes... If u want, I can send it to the list... It is quite short...

Furthermore u should turn off any power saving feature, if u want to use pvr250
port, because the driver seems to hate power saving...
