I wanted to purchase a DTVpal last year at this time. But the DTVpal had several bugs last year ( I don't about now ). I choose the TIVO HD and never been more happier with a home electronic equipment.
I can record Canadian analogue broadcasts and digital one OTA. Someone told me that you cannot record analogue broadcasts with the DTVpal but I cannot confirm that.
The Tivo run 4 to 6 hours at my home during the week. Not one bug.
