The Sony unit you mention is a professional unit and it will record an image with about 300 lines per picture height (which is the standard way of expressing resolution in TV land --- specify how many alternating lines of 0% black and 100% white can be resolved on a horizontal line in a distance equal to the picture height.) I don't know where you got a spec like "250 lines per inch" but it's totally meaningless unless you're talking about a particular display (and then it had better be a rather small one!). The 5850 is an excellent machine and is light-years away from VHS or Beta as far as image quality, stability, and yes ruggedness. -- Robert Bickford {hplabs, ucbvax, lll-lcc, ptsfa, msudoc}!well!rab terrorist cryptography DES drugs cipher secret decode NSA CIA NRO IRS coke crack pot LSD russian missile atom nuclear assassinate libyan RSA The above is food for the NSA line eater.
