Problem for analog TV with vlc 1.0.0

Hello to everyone!
I have been using vlc to watch analog TV without problem until I installed vlc 1.0.0. I have a dazzle TV hybrid stick with mcentral.de drivers. When I plug the stick to an USB port the driver is loaded and creates a /dev/video0, /dev/vbi0, /dev/dsp1 and /dev/dvb/adapter0/{demux0,dvr0,frontend0,net0} devices. With vlc version < 1.0.0 I used this command for analog TV

vlc v4l2:// :v4l2-dev=/dev/analogtv :v4l2-adev=/dev/tvdsp :v4l2-standard=2

where /dev/analogtv and /dev/tvdsp are symbolic links to the appropriate devices. I use v4lctl or other commands to tune. With vlc 1.0.0 the above command doesn't work anymore, no video and audio. I've only been able to see video with this command

vlc v4l2://:v4l2-dev=/dev/analogtv:width=640:height=480

that is to say I have to specify width and height, but no audio. Even adding :v4l2-adev=/dev/tvdsp and other v4l2 audio input parameters doesn't solve the problem. The only command I have found that gives bot video and audio is

vlc 'v4l2://:v4l2-dev=/dev/analogtv:width=640:height=480:v4l2-standard=2' :input-slave=oss:///dev/tvdsp

but the video is so choppy that's useless. Any suggestion is welcome.

vlc v4l2:///dev/analogtv

But why not using dvb:// ?

The "vlc v4l2:///dev/analogtv" doesn't work unless I add ":width=640:height=480", like the "vlc v4l2://:v4l2-dev=/dev/analogtv:width=640:height=480" command, I suspect they're the same. About dvb, unfortunately in my region (Sicily - Italy) some TV stations are not broadcasting in digital, only analog. Among the analog-only stations there are the state owned RAI TV channels.
