Hi,

If you don't feel like patching Myth (like if you installed from mdz's 
Debian packages), you can use it by creating a wrapper script and 
changing the cron entry for mythfilldatabase:

1. Register for DataDirect

2. As your mythtv user, run tv_grab_na_dd --configure

3. Create the script /usr/local/bin/mythfilldatabase-dd with contents:

#!/bin/sh
# the name of your DataDirect lineup
lineup="Cox Communications"
# the ID of the MythTV videosource (usually 1 -- check your database)
sourceid=4
tmp=`tempfile`
tv_grab_na_dd --lineup "$lineup" --output "$tmp" --old_chan_id &&
mythfilldatabase --file "$sourceid" -1 "$tmp"

You technically don't need to specify --lineup if you only have one 
defined, but it doesn't hurt.

4. Change your crontab to call mythfilldatabase-dd instead of 
mythfilldatabase.
