This is a common problem. When you run the command, the output file is opened (and overwritten) before you start to read the input, which by now is null. You command then exists as it finishes reading no input.
You will need to read the input and write to a separate output file. If need be, then rename (and overwrite) the input file thus:-
It does mean that you have to consider space for having the two files at the same time, even if just for a moment.

tv_split
TV_SPLIT(1p) User Contributed Perl Documentation TV_SPLIT(1p)NAME
tv_split - Split XMLTV listings into separate files by date and channel.
SYNOPSIS
tv_split --output TEMPLATE [FILE...]
DESCRIPTION
Read XMLTV listings and split them into some number of output files. The output file chosen for each programme is given by substitutions
on the filename template supplied. You can split listings by time and by channel.
The TEMPLATE is a filename but substitutions are applied: first %channel is replaced with the id of a programme's channel, and then
Date::Manip substitutions (which broadly follow date(1)) are applied based on the start time of each programme. In this way each programme
is written to a particular output file. When an output file is created it will also contain all the channel elements from the input.
One or more input files can be given; if more than one then they are concatenated in the same way as tv_cat. If no input files are given
then standard input is read.
EXAMPLE
Use "tv_split --output %channel-%Y%m%d.xml" to separate standard input into separate files for each day and channel. The files will be
created with names like bbc1.bbc.co.uk-20020330.xml.
