With how hard the car was to start in your after video you're compression numbers are a bit surprising, especially when you went to restart it and it still didn't want to start. You either have really bad blow by that is giving you false compression numbers, you need some new glow plugs, or your timing is way off. With comp numbers in the 300's you shouldn't have to try to start the car 3 times. It should fire right up, unless your glow plugs are bad or timing is off. Bad glow plugs can cause more smoking on start up due to the fuel not being burned completely. It looks sunny in your video, and it appears your not wearing a big coat which tells me that you are somewhere fairly warm which makes me thing your GPs aren't the issue. When you did the compression test did you turn the engine over several times with the injectors out to blow out any fluid in the cylinders?
