Dish Network has stopped selling its DTVPal DVR, after weeks of offering it at discounted prices. Unfortunately Dish has no plans to replace it.
The DTVPal was the only affordable over-the-air ATSC dual-turning DVR on the market, but lacked some important features which I guess goes to show you sometimes price isn't the determining factor.
The method used to record programs wasn't very user friendly as you had to schedule recordings by time slot and channel, rather than show not to mention you only received limited guide data over-the-air.
Hopefully something new and better will come along shortly.
