Should I be that bothered abut getting a DVD recorder with progressive scan output capability. Does it make that much of a difference in picture quality. Is it only useful for large (eg. 42 inch +) plasma displays or would I notice a difference on a 32/36 inch CRT TV with component/progressive compatibility. Also, this may be a dumb question but is progressive scan only compatible with pre-recorded DVD movies, or would I notice a difference with stuff I have recorded onto the HDD or DVD myself.
