In short, you get to dig in and read...
That seems to narrow it down to your camera. My bet (I often lose) is that you have the USB hookup and may need Firewire to get it off the ground.
I do not have a TRV22, but have Suse 9.1 and a JVC unit on USB 2.0 and soon firewire. Since I wanted to not battle this but create some videos I just used Windows. Some have other goals, but I wish you well.
I am new to Linux and wish to use my Sony Handy cam with SuSe. I am able to pull off still photographs from the memory stick but can not find a programme or driver that will allowe me to see Video film.
Can any one enlighten me.
I'll be most grateful.
