Well, I have to concur with ral-clan that the best option would probably be to capture the video from the miggy via comp. out, or to use UAE.
As for blurry/jittery pictures... Well almost every digicam I've owned seems to need too much pressure to depress 'the button'. My Olympus FE-180 has an image stabilization mode, which can help, but it's far from perfect. One of those tiny digican tripods might help too, tho', IME the legs on them can be a bit 'rubbery' , and you may still end up with a blurry shot because you had to push so hard on that !@#$%&! button.
For my dad, the biggest 'selling point' of the Olympus FE-180 was that it had an AV out cable.... he would hook the camera up to the DCTV on his A1200 and just grab the picture that way. Not nearly as good a picture as loading it directly, but still pretty cool.....
About Sony.... Uhhhh, I dont want to say too much... I might make my Sony Beta machines angry
But, I will say that, quality-wise, current manufacture consumer electronics by Sony can be very hit-or-miss .... It might work when you get it unpacked, maybe not. Maybe it will die 1 week/month/year later..... It's sad really, I know Sony
CAN make reliable, good quality products.... they just can't do it on a regular basis.... OK, I've never owned any pro or semi-pro video equipment by Sony, so I can't say about that....
