[QUOTE="kiwijunglist, post: 983044, member: 76888"] Yes it will use the analog hardware encoder on the tuner to turn the analog tv signal into MPEG2. If you are only recording then the analog signal is encoded by the hvr2250's hardware analog encoder into mpeg2. The MPEG2 stream is then written straight to the HDD. If you are watching Analog TV/Video then we have Analog TV/Analog Input -> HVR2200 MPEG2 Encoder -> ... -> MPEG2 Decoder (eg. LAV codec) -> Display I think you mean to say decoder here? Software decoding is done via the CPU Hardware decoding/Hardware acceleration (CUDA/DXVA/etc) is done the GPU (eg. GT210 / HD4250) Swapping your video card, wouldn't make any difference if you were using software decoding. Decoding MPEG-2 is pretty easy, don't need a fast CPU or GPU to do this. [/QUOTE]
