TiVo does officially support Canada now, listings and all. But they don't sell any hardware here. And you're stuck paying up to $20 per month just for the listings data and their arbitrary decisions on what you can or can't do with what you record.

I don't mind a lack of automated commercial skip in SageTV. That's a post-processed procedure on any box so it can definitely be supplied with a plugin. I normally just use its built in manual skip features. Their jump time is configurable but I use the defaults: 10 sec and 2:30. This lets me jump commercial breaks very easily when watching recorded content.
