For those who stumble across this thread, looking for a simple DVR but have no internet access, I agree with other members that the I-view, Homeworx, and Ematic devices seem to be the only remaining systems available.
The ChannelMaster DVR+ was the king in this market, with a well thought out design, premium hardware, and a serious amount of fans. Unfortunately it has been dis-continued, but, there is a thriving used market for these. As they access PSIP data, (coming from the same signal as the TV broadcast), they still have functionality after the TiVo/ROVI issue the OP mentioned. These devices can demand a high price when found in the used market, so be forewarned.
ChannelMaster does have a cheaper alternative to a used DVR+, the CM-7004, it has a single tuner,
records to a USB stick, is easy to operate, and does not require an Internet service for guide data. It regularly goes on sale for $49, but is most often sold at $69, and is not necessarily any better than the iview, or Homeworx devices that are less expensive.
