The reference to deinterlace is due to the fact there was not a way to overlay the dvb subtitles onto a screen BEFORE resize/encoding, so as deinterlace was done before resize/encoding i added code into the same function call, this added subtitles onto the screen so that they were burned on. 

Hope this clarifies the reasoning
