Anyone recommend a good all in one DVD Burning Package for doing films from the different formats (avi, MPEG4 etc) so I can watch them on my TV. I had a go with DVD Santa but it just keeps crashing at the beginning of a conversion.

you asked for a burning programe then say you have tried dvd santa which converts different formats into vob files. it will also burn said vob files but is sometimes a bit temprromental.
The no 1 burning proggy has got to be nero. as to what proggy you use to convert the files there is an abundance of ones to choose from Win Avi, Tempeg encoder. are two I use regulary.

Hope this helps
