I have the exact same problem with one particular TV series... probably the same one... It plays fine on my computer, but when burned it does exactly what general T described.
I have burned loads n loads of full length video files with Nero 6 and they have all been fine... its just this particular series (downloaded from the same uploader).. it did make me think that maybe the uploader/sharer did something to the file to stop people from burning it and maybe attempting to sell it????
I have looked into the SUPER converter but when I read through it all and went to download it, it says you must have 20GB free hard drive space which I simply do not have... and therefore couldn't use it.
General T... let me know how you get on. Cheers.
