[QUOTE="mm1352000, post: 787569, member: 82144"] Hi Srikanth Yes you are wrong. GPUs do not encode. Encoding is the process of converting one format into another, like converting an analog s-video signal into an MPEG 2 video stream so that it can be stored or manipulated in a PC. The Colossus can encode, but not the GPU. Your GPU does not support hardware accelerated h.264 decoding. Exactly - the GPU has nothing to do with the HDMI input feed. Let us be clear: with the same number of bits you can store higher quality video with h.264. h.264 is generally used for HD because it takes less space than MPEG 2. I also agree that it is unlikely that the channels are all provided in h.264, but something is re-encoding to h.264. If I had to guess, I would say it is the Colossus. What you have called "upscaling" is re-encoding. Converting from MPEG 2 to h.264 is an encoding process. Upscaling is resampling the video resolution - for example, converting from 720x576 to 1920x1080. That is possible if the Colossus is encoding the signal. I have no idea, but Windows is wrong. TS files are technically MPEG-2 [systems] transport stream files. MPEG 2 in that context is not the same as MPEG 2 video. Very confusing... Probably.
