TiVo makes the DVR with the most widely recognized user-friendly interface.
The most popular and reliable brand of DVR recorders would be TiVo.
Virtually every DVR offers off-site scheduling which can be done through cell phones, a user account on the internet or even PDAs and iPhones.
The Comast DVR has a different interface, while the DirecTV DVR has an arguably better user experience.
It will depend on the brand of the DVR. Different make has a different specs on it. So i would recommend doing a search on which kind fits you best. Keep in mind that DVR will be on most of the time, since it needs to be on for the duration of the show.
Only TiVO brand DVR's are capable of that feature at this point in time. Hope this helps!
Samsung and LG both offer multiple models of TV/DVR combinations. Other makers will soon follow. No but Miglia Alchemy does have a TV DVR
One of the most popular recent additions to the home entertainment system has been the digital video recorder (DVR). The DVR normally comes as a complement to either a digital cable or satellite cable television service. The DVR has many features that drastically increase the television viewing experience for its users.  The main feature of a DVR is that it can digitally record television shows. A DVR user can look through their digital cable guide and easily select shows that they want to record. When the show begins, the DVR will record the program. Through the use of a DVR, the user can stay caught up on all of their favorite television programs, regardless of whether they are home when the show originally airs. Many new versions of the DVR can also record up to four different programs simultaneously. Depending on the model of the DVR that is purchased or rented, the DVR can hold up to 40 to 80 hours worth of programming at once.  Another feature of a DVR is that the user can pause live TV. In the event that a DVR user needs to step away from the TV for a few minutes, the user can actually pause the program while they are watching and resume the program when they return. If needed, the user can also rewind the live television program to re-watch a play of a game or a scene in a show. When watching a program that was recorded through the DVR, a user can fast forward throughout the recording. This means that a user can avoid watching commercials, which allows them to finish watching a show much quicker than if they were watching it live.  The third feature of a DVR is that they can be accessed while you are away from your home. Depending on your television service provider, you may be able to access your DVR anywhere in the world through the internet. When accessing your DVR online, you can find new shows to record, set up series recordings, or delete programs that are presently sitting on your DVR. Â
Check your DVR's user manual for navigating through the Display mode. Every DVR will have a different process for navigation and viewing multiple channels.
To erase a recorded video from a DVR, navigate to the "Recorded Programs" or "Library" section on the DVR menu. Locate the video you wish to delete, select it, and look for an option such as "Delete" or "Erase." Confirm the deletion when prompted, and the video will be removed from the DVR's storage. The steps may vary slightly based on the DVR model, so consult the user manual if needed.
With Dish Network, yes. Your user guide will show you how this process works.
There are many websites that offer reviews on HD DVR receivers. I would recommend visiting the consumer research website as it not only offers reviews from consumers, but also expert. You can access their website at www.consumerresearch.com/dvr-reviews.
When you erase a program recorded on a DVR, the data associated with that recording is marked as available space, allowing the DVR to overwrite it with new recordings. The actual data may remain until it is overwritten, but it becomes inaccessible through the user interface. This action frees up storage on the DVR for future recordings.
