Thank you to everybody for the time you've dedicated in answering to me..
first of all i've made a mistake...i have a HV30 and not the HV20...but if i remember fine there is not so much difference between the two models..
1) Am i worried about the tape...?
You are right..i'm little worried about the life's tape mechanism...and for this reason i'm planning to put all my tapes (roughly 50) into my NAS..
So i'm thinking to have more flexibility having a camera that write the files directly on a memory..(SD, CF, or SSD)..
2) i never used a Card inside my Canon HV30...and now i've no one "miniSD" card...so...
a) i bought a Transcend MicroSDHC 8GB memory card with 2 adaptors (SD e MiniSD) for 8 Euro....
3) Thank you very much for your useful information about how to use the HV30 (or HV20) in manual mode)
The question is...until i'll receive the card...do you think it's possible use your instructions..?
for this particular need i wear an old (2 years...) "Contour 1080p"

My wyfe use the Canon HV30 from a safe place..on a tripod..
you too are thinking thats an higher frame rate would be useful for action sport shhoting..?..
if i have right understood your opinion (i'm sorry but i'm not so confortable with English..)
a) you disagree with the Markr041 opinion..and you think that the progressive mode id not useful..
b) you are using your Panasonic GH2S with the output 1920x1080 at 50i with good result..?
I'm waiting your comments...thank you very much to you all for you time..
