Under a different thread we started getting a little off topic in discussing the hardware platform of the R15 compared to DTV's previous DVRs. In particular: and I had looked into the R15 and there has been other posts detailing some of the R15 specs so I thought this may be worthy of a discussion under it's own topic. The R15 includes: The STi5528 Chipset from STMicroelectronics. This includes a ST20 166MHz MPEG2 decoder and a ST40 200MHz application processor (for OS and scheduling and such). 32kB EEPROM 8MB FlashMemory 64MB DDRAM 160GB IDE HD V.90 Modem 2 USB 2.0 ports Other Receiver/Audio chips Those are facts provided in a link ferrg provide which is here. For more info on the STi5528 you can check here. I'll do some searching on the other DVRs that chrishiatt1973 mentioned. If anyone has info regarding these systems (I guess not the DTV branded or Hughes versions) feel free to share. Also, I attempted to find the same info regarding the R15-300 manufactured by Phillips without any luck. Can someone with a Phillips R15 please note the FCC ID # on it and post the info here? Thanks.
