why does it skipp so much

i have some sk8 boarding movies i burened onto a dvd r and at the last 30 mins it starts skiping y does it do that im using convertxdvd the free version and im using a dvd r iono but the brand is esa

 

ESA is bad media, try Taiyo Yuden, Verbatim, Sony (Made in Japan) or Office Depot's house brand. Burn at 1/2 the rated media's speed, and defrag your hard drive quite often. Also, check your DVD burner's firmware, make sure it is the most current.

I hope that this helps.

 

Also watch your compression if your transcoding

 

also if these are downloaded files from the internet then you have to make sure it's playing fine and the conversion isn't going to adjust it too much to make the files corrupt where they act funny, like skipping and pixelate or freeze. soooooo consider where the file came from and understand sometimes you get garbage and you try to make champagne, it doesn't work!

 

That would be my guess as for the cause of this problem.

 

I agree, the media is most likely the problem. The conversion process will not cause it to skip, but will and may cause pixalization.
