No TiVo brfore a series 3 will record digital signals they only have NTSC tuners so they need a converter box. DTV PAL combined with a series 1 TiVo is the best combination I have found.Dug up an old thread looking to record OTA channels mainly RTV and Antenna TV. Will the Sony SVR-2000's record digital OTA signals?
31.4 and 33.2 have to be manually recorded because they don't have guide information. Ant TV has a much better signal than RTV but I can get both at 61 miles from towers.
