Are all programs about the same when it comes to capturing miniDV footage to a HD uncompressed or are some better than others and/or does one stand out?

I use pinnacle studio 8 right. Thought just copying it over it almost looks as though I see blocks or am already losing quality.

Also when I play in WMP the picture is very tiny but the sound is fine. In powerDVD the picture is fine but the sound seems to crack a lot with tons of static. Could it be my capture program?

If there anything I can easily improve upon? Picture quality is my main concern.

This is coming from a Sony TRV-38 BTW.
