I want to capture live TV (EuroSport ~ PAL analogue satelite). Was wondering wether an ADVC-55 would do the job. Captured to DV format to PC's hd, via firewire. Is this okay?

Want to do unattended captures through-the-night.

I guess the other option is a DVD recorder, using dual-layer discs, might get 4hrs (but at inferior quality). Or DVD recorder with built in hard-drive capture. ADVC might be the cheapest option, plus I'm not restricted to 4hrs.
