The problem is a modification they made in the driver's dvb.c.
I don't know why they did this (I assume they had some reason...),
but if you change it back to the way it was done in driver version 2001-06-18
it works again.

Locate function play_iframe() in DVB/driver/dvb.c and replace it with this
version from the older driver:

-----------------------------------------------------------------------
#define MIN_IFRAME 500000

void play_iframe(struct dvb_struct *dvb, u8 *buf, int len, int nonblock)
{
        int i,n;

        if (len>=MIN_IFRAME)
                n=1;
        else
                n=MIN_IFRAME/len+1;
        dvb_play(dvb, iframe_header, 9, nonblock, 1);
        for (i=0; i<n; i++) {
                dvb_play(dvb, buf, len, nonblock, 1);
        }
}
-----------------------------------------------------------------------
