When we purchased our HD TV a few years ago we decided to upgrade our Time Warner Cable DVR to the HD DVR. Having the HD DVR allows us to watch certain channels in high definition. The HD DVR always allows us to record two shows at one time while watching one of the shows recording. There is a problem that we seem to encounter whenever we try and record shows in high definition. At times when we have a show set to record in high definition a message comes up on the screen saying "not enough disk space - can not record show". I can then turn to the non high definition channel to try and record the show - and it records... We do not understand why a show will not record in high definition but the same show will record on the regular cable channel.
The channel guide is really easy to understand and operate. The guide shows what time and channel a show will be on. It also describes what the show is about.
The HD DVR does have a USP port on the front of the box but there is no directions on how to use it.
