Detailed Description

This is a specialization of DTVRecorder used to handle streams from ASI drivers.

This has been written and tested with the DVEO ASI hardware and drivers. Those particular drivers do not come with udev rules so you will need to create the following rule in /etc/udev/rules.d/99-asi.rules

SUBSYSTEM=="asi", OWNER="mythtv", GROUP="video", MODE="0660", RUN+="/etc/udev/asi.sh" OPTIONS+="last_rule"

Also, create a /etc/udev/asi.sh file with the following contents:

#!/bin/sh

for VAL in buffers bufsize dev granularity mode null_packets timestamps transport uevent clock_source; do
  chown mythtv /sys/devices/*/*/*/dvbm/*/asi*/$VAL ;
  chgrp video /sys/devices/*/*/*/dvbm/*/asi*/$VAL ;
  chmod g+rw /sys/devices/*/*/*/dvbm/*/asi*/$VAL ;
  chmod g-x /sys/devices/*/*/*/dvbm/*/asi*/$VAL ;
  ls -l /sys/devices/*/*/*/dvbm/*/asi*/$VAL ;
done

Be sure to mark asi.sh as executable with "chmod a+x /etc/udev/asi.sh" udev will silently ignore it if it is not marked.

This of course assumes you want MythTV to have access to all asi device, if this is not the case, you will need to write a more specific rule and modify the asi.sh to only grant permission on a specific asi revice
