OK, I've just bought the Pioneer multi-region recorder (640) with the 250GB hard drive. I love it - no problem hooking it up, setting times, editing HDD, etc. It's the simple act (or maybe NOT) of setting the PR to record one channel while watching another that has me totally stumped! Every time I try it, I either get the channel I'm watching or snow. When I leave my TV set to the channel I want (overnight, while I'm out), the movies record perfectly. But I can't record on the HDD while watching another program. I KNOW this is possible. The manual with the Auto Tuner and Manual Tuner makes no sense to me - as what logically would seem to work...doesn't. What am I doing wrong...and how can I remedy this. I'm hooked up to a Cablevision box. Someone help!
