I have a 60" widescreen TV. Viewing miniDV shots direct from the tape already show pixelation. MiniDV format, by itself, is not adequate for big screen TV's.
When transfering S8 to miniDV, you will even add resolution loss due to encoding to mpeg to be able to view it in a DVD. This is unless you save the miniDV in lossless .avi or leave it in tape. In short, telecine transfer to DVD is just a viewing media but not for archival. Either save the moviein an .avi (expensive because of large hard disks) or leave it in tape.
The future will be the use of HDTV camera. The resolution even when transferred from S8 should be wonderful.
