DVD VHS Combo Players

The VCR works fine but the DVD player won’t load anymore movies and when I try to play them, all it says is that the disk is bad.

when i convert youtube video’s to mpeg2, please tell me why when i go to play in certain dvd player it says no disc or and just don’t read, is there a certain format i need to do other than mpeg2 in order to watch my dvd video’s on any and all players?

I want to know if i can play hi def dvds on my 3 year old dvd player, or will i need to upgrade my dvd player?

I went to a concert and the video of the show is on youtube. How do I go from those webpages to video on a dvd that will work in a dvd player?
Any information on how to get the audio into mp3s would be great too.
Something free would be great.

is there a way to burn a movie downloaded online to a dvd that would play in any dvd player? If so, how? I have movies stored on my pc and I would like to burn them to DVD so everyone can watch them. And how would it be with resolution?
