|NO Tivo or DVD recorder with it.
Tivo is currently the best DVR software, so I am a bit confused by your post. Perhaps you mean you want a DVR that doesn't require a $5/mo fee?
The appropriate forum for HDTV DVRs like the HDTV DirecTivo is the HDTV Recorders forum
The LG 3510 is the only feeless HDTV DVR available for purchase. It works with off-air signals from an antenna. It costs $600 and has one tuner, so you can only record or watch one program at a time; you cannot record one program while watching another. It will not work with the encrypted channels on your cable system. It requires no monthly fee as it uses the free TVGuide software, but as you might expect, the functionality and usability of that free software is very, very limited. For instance, you can't record a program while watching a previous recording.
If you want to buy your own HDTV DVR to record one program while watching another, your only options are the $899 HDTV Tivo
from DirecTV and the $999 Dish 921
from Dish Network. Both of these will let you record one channel while watching another; both will also let you record two satellite HDTV channels simultaneously while watching a previous recording (though only the HDTV Tivo will let you record two HDTV local channels simultaneously). Both record the original digital signal from satellite and an antenna, so recordings are 100% identical to the original live broadcast. Both have the same $5/month DVR fee, which is waived entirely if you subscribe to their top programming package.
