Hi

I have a pioneer a03 and have managed to copy a dvd silver that i bought at a car boot and the copy will play in my standalone dvd player without any problems.
A friend of mine managed to get a 1 hour tape out of my camcorder and put it on a cdrom for me.
The camcorder film is mpeg-1 and i have managed to burn this to dvdr and put in a few menus etc using spruce up.
The problem is that the dvdr will then not play in standalone player but will play in a friends standalone.
I am using exactly the same dvd-r discs on both films.
So my question is - why does the dvd silver copy perfect and play but the mpeg-1 converted to .m1v will not play - and is there any additional thing i can do to recorrect this problem ?
thanks in advance
Andy
