I have been using kmttg to encode Tivo video to hb_television (mkv) format. I like it a lot. Many thanks to the developer. However it takes a long time to perform the encoding. Twenty episodes of The Big Bang Theory takes about 2 days to transfer and encode. Some fan in the PC spins up so fast it sounds like there is a weed whacker in the living room. I believe the fault is with my hardware - AMD Athlon II x64 CPU 2.80 GHz, 4 GB RAM, circa 2010. If I were to build a new PC what hardware should I use for the fastest encoding? Do I want an Intel i7 CPU or will an AMD CPU suffice? Does the graphics card perform any processing? Any particular graphics card? I would use a minimum 8GB RAM. Do I need more? Thanks in advance for any suggestions.
