Yup, Dvico Fusion Plus DVB-T PCI HDTV.
Each recording is around 9gb. Remove the adverts and its down to around 6.5gb, use dvdshrink and it fits perfectly on a 4.5gb dvd-r at around 70-75% compression (Sandown I split over 2x DVD-R and no doubt Bathurst 1000 will be about 5 DVD-R's ) with awesome playback quality.
If Ch 7/10 made full length, full season DVD's available of each race, every round for every year i'd happily purchase them, until they do i'll happily do this
