I love your sig, yeah despite all the problems its right in my ballpark for price and I have just standard cable as well. I heard you can still set the timer or do vhs style recording on the digital channels, just you dont get the tivo like interface. I might call a support number and see if they know the difference between the 7000 and 7005, i found 2 different PDF instruction books, on was the old 7000 on rcascenium and one that says 7005 on yahoo when searching for rca drs-7005 in the search. From what i can tell they are the same though.
lol i was checking the pages and one difference was:
7000: Since this product can do alot of neat stuff...
7005: Since this product is multi-functional...
found a real one: page 28 talks about the mp3s, the old one talks about the flash device on the usb to transfer and the new one does not. ok after reading it the main difference is that the 7005 does not have a usb port for using a MMC reader to transfer jpgs or mp3s, you have to do that with a CDR, they also wrote some of the menu system differently and the bottom is C 2003 instead of 2002. Didnt say anything about a firmware update though. If they removed the usb and such from the menu there might be a chance that they fixed some problems.
