just transferred a load of home videos from sdhc card to pc

Were they blue, out of curiosity?

all clean unfortunately

Were they from 1982?

If you want practical advice you should try to post (well) before midnight. Here there be monsters.

No idea why it should be out of sync, i presume the card came from the camera.???
Are they hi def cos some of that does stutter and run wont run smoothly if you haven't got a decentish PC.
But not heard of slow motion tho.
Unless it's been recorded at 60 frames per second for instance and played back at 24, 25 or 30 frames per second.
But only guessing.

cheers randolph it is di def yeah...any way around this mate

What you need to do to start with is connect your camera up to the tele (with card in camera) and it should play perfectly.
You have probably done that eh.?
If not do it just to prove the point.
I'd suspect your pc just isn't up to it to start with.
This hi def footage is a new typr of movie compression and lots of people are having difficulty with it.
Some convert it to another type of file to get it to run smoothly or to try and get an editing program to accept it.
But i'd start wiv pugging it into your tele first and then perhaps Google the problem.
