Infinite transcoding, if encoding time exceeds cron

Hi,
first of all i want to thank you for this awesome module.

I have set up 3 different presets to encode uploaded videos via ffmpeg (flv, ogv & webm) and a cronjob, that runs every 5 minutes. Whenever the the transcoding-process exceeded the 5 minutes, a new ffmpeg-process started, resulting in multiple files named filename_0.*, filename_1.*, and so on. After taking a look at the database i saw in the 'video_files' table, that the 'status' remained 1 while encoding. digging a little deeper, i found the following line in video_ffmpeg.inc:

//$this->change_status($video->vid, VIDEO_RENDERING_ACTIVE);

After uncommenting that line, everything worked as expected. Are there any unwanted side-effects implied in doing so? I didn't encounter any so far.
This also affects 6x-4.2alpha.
Thanks again, keep up the great work!
