does smp allow VOB files to be converted??

I says yes but I am unable to  files to be converted do not show up

No, VOB files are from DVDs; you have to convert them (and maybe merge them) with other software first, before SMC can do the final conversion and transfer to your player.

VideoDownload Studio support any video to sansa, it can convert VOB to avi, mp3 for sansa.
