VHS to MPEG2(DVD) with transcode or mencoder?

I want convert my VHS records to DVD. I am installing transcode, ffmpeg, mplayer (with mencoder) and more, and attempting with this command:
mencoder -tv driver=v4l2:device=/dev/video0:normid=0:input=1:amode=0 tv:// -o /home/rade/radni/output.mpg -of mpeg -oac lavc -ovc lavc -lavcopts acodec=ac3:vcodec=mpeg2video:vhq:keyint=25:vbitrat e=3000:abitrate=160:scplx_mask=0.2 -vf scale=720:576, but it is, however, avi header. What's wrong?
I dont know to work with transcode (I am installed transcode with enabled v4l2 driver), and I need sample commands for convert signal from VHS video player to MPEG2, without any afterwards reencoding, i.e. MPEG2 which accept dvdauthor.
My english is too bad, sorry.:?
Thank's.

There's a GUI version:

It allows you to easily encode and burn in a variety of formats.

Thank you.
I am find this: http://gv4l.sourceforge.net/ :
" What is Gv4l? Gv4l is a GUI frontend for the V4L (Video For Linux) functions of transcode, used to record video (and audio) streams from a V4L devices, such as tuners and webcams, in encoded (Xvid, DivX, etc.) or raw video formats. "
That is all what I need.

or visit VHS to DVD and copy your home video tapes to dvd. You can get a pretty good conversion at a reasonable price from a lot of places. But what are most of these companies lacking? Care and attention to detail! Other ways you get totally amateurish product done with domestic equipment.
