Hi I hope this is the right place for this query. I am trying to convert some HD mkv files to DVD. I am using AVI2DVD following the guide on this website. The problem I have is that when I view the DVD, it plays at full screen (16:9), but everything looks stretched vertically (as it would if watching a widescreen program squashed into a 4:3 ratio). I have also tried playing the same files by streaming them to PS3 and they look the same. When I view on my PC in Media Player, they play fine, but don't appear full screen (they have large bars at top and bottom). I am, therefore, assuming it is something to do with the file type. My question is, can I convert these so that they will show the bars by default, as they do in Media Player or make it full screen, but at the proper aspect ratio (not stretched). I cannot simply change the my TV aspect ratio, as it doesn't work. The video remains stretched, whatever format I use. Any help would be greatly appreciated. Thanks.
