Having tried both, I am all for the Bt848. >From the data sheets it looks like the Bt848 is much more powerful for what concerns sampling and filtering. As an example, it can average adjacent rows to remove artifacts due to phase errors in reconstruction the color subcarrier -- a common problem in PAL which is usually solved by the use of a delay line, but the Meteor cannot do this (and yest those artifacts I am able to see here). It also seems to have a higher sampling frequency. Last but not least, Bt848-based boards cost 1/3 of the Meteor and there are many suppliers. > Can one recommend a Bt848 based card ? I have had good results with the Hauppauge board.
