good Digital Video Cam?

Hi,

I am tired from my old hi8 sony C.camera and need to upgrade to digital V.cam I have some questions..

1.how does the "effective video pixels" affect the video quality? I noticed that for example the Sony trv22 has 340,000 effective video pixels while the trv33 has 690,000 pixels . can u see the difference really on tv? I mean the tape has 500 line max standard.

2.it is strange that the camera has 690,000 pixels effective but unable to produce 640x480 videos using mpeg capture what is the use??? the 320x200 is very low for full screen... what benifets do I get from getting a didgital video cam then??? if it supports only small screens in digital?? I d expect at least DVD quality capture or 640x480 any video cam support this???

3.even some cameras with 3megapixels still and 2 video, the digital streaming is also 320x200 what is this???

4.If I need to store the movies to my PC using USB , does it support DVD resolution???

5.whic one is really better a normal V.Cam with video capture card or a digital one ??? and is the quality of the movie better if I used a vapture card even with Digital cam??

6.any recommendations plz? I aim at the SONY trv33 and trv22 the only differnce between them is effective video 340,000 vs 690,000 does it really show or affect the output to pc via usb or FW???


7. I dont care about still images I find it stupid cos my canon a70 outperform any combo V.cam

any help or Ideas please?

also, I heared that Sony doesnot have mic wind noise filter.. I really cant decide any expert here please?

thanx in advance
