The solutions above are good from the suggested converters to an older computer converted into a media center.
My main wide screen TV has USB input . I just use a regular 1 HDD docking station.
The TV apparently can play several video file formats. So I don't even need a media player.
On the DVD compliant format there is a slight "pause" as it loads each .vob seperately. This is something I can live with .
With .avi of .mkv it plays the complete file.
I do wish it would play from .iso .
