It's unwise to use an odd number of lines, especially if you want to watch
movies in full-screen. You should use a resolution that is divisible by 4.

There's no "i915" driver. There is "i810" and there is "intel".
Which one is it? Did you set the "CacheLines" option appropriately?

What part of "maximum is 1024x1088" don't you understand?
You're trying to play a movie whose resolution is beyond
your Xv driver (or hardware) capabilites. You need to scale
it down (i.e. -vf scale=1208:-2)
