 Subtitle data coming from EIT with newines, is added with new lines into
 the database.

 When trying to download the ASX Stream file from Mythweb, it is generating
 the Browser Error:
 ----

 Issue is, that the new lines are added to the table, see below snippet:

 mysql> select title, subtitle from recorded;
 +----------------------------------------------------+-----------------------------------------------------------------------------+
 | title                                              | subtitle

 In the last entry you can see the added new line, which is causing the
 issue.

 ----

 After updating the subtitle column in the recorded table to have only one
 line, all is working fine.

 mysql> update recorded set subtitle ='Der Cha-Cha-King wird 40' where
 subtitle like 'Der Cha-Cha-King wird 40%';
 Query OK, 1 row affected (0.00 sec)
 Rows matched: 1  Changed: 1  Warnings: 0

 mysql>


 ====

 Solution:

 Make the function more robust to change all taken values into one line,
 before adding to the Database tables.
