Actually interlaced video kinda makes sense for sports and other live
video.. you get 50 fields per second, so the movement is smooth..
If you look at interlaced video on a progressive display, then you need to do
heavy deinterlacing, preferrably using "full motion" methods to get 50 or
100 fps output.. takes a lot of CPU. Check http://www.100fps.com
Where did you get that stream from btw?
Digita is broadcasting this channel as 720p in DVB-T.. dunno if it's 25 fps or
Hopefully not 25 fps..
In what format is that Arte HD?
