I like to record several hours of XM radio off my Direct TV receiver onto a disk for playback in my car. Of course all the songs run together, with little or no gap between them. Without some way to mark tracks, I would only have one 5-hour track and skipping individual songs would be a huge pain. I can't use automatic track marking, since the gaps are too short, and I also don't want to stand there and manually insert a track mark every few minutes. My portable unit allows me to have a track mark inserted every 5 minutes (or more if I want) automatically. This is a great feature but so far I've only seen it on portable units. I'm looking for a home deck that has this same feature. Does anyone know of a model out there that does interval track marking? Thanks!
