HI guys, 

I have this really weird problem. I've rendered my project i've been working on and wanted to play it on my tv. First it went well and nothing was wrong. However i noticed some mistakes in my video and wanted to delete them and add some more text. I've rendered it in the same format (mp4) and with same rendering settings . When i want to play it on tv, the video (50 min long) lasts about 15 seconds and then it crashes and can't be played anymore. However, the first video still works. I wonder if its problem with the tv or with rendering and as i said, both videos are in the same format (mp4). Oh and on my computer both videos works fine.

Thank you for any respond.
