[QUOTE="mm1352000, post: 788141, member: 82144"] Hi again Srikanth Yes, it does seem high. Have you tried CBR mode to see if the encoder adheres to the settings? VBR is much more difficult to check as the encoder will use higher bitrates for high motion scenes. This is difficult from our perspective because your video is always arriving as h.264 - we can't automatically tell the difference between HD and SD. My understanding is that it *may* be possible to set the bitrate on a per-recording basis. I have never tested this, but try: 1. Open MP. 2. Go to the TV section. 3. Click "scheduled". 4. Click "new" on the left. 5. Select "advanced record". 6. Select the channel. 7. Select the recording type (best to use "record once" for testing). 8. Select date, time and duration details. 9. Select the bitrate mode. Pick a different one from the playback and recording settings so that we can tell it really works. 10. Select the quality. Again, best to choose something different here. Does that allow you to set the quality of each recording as you desire? Please provide logs to prove either way. The big deal is that HDMI is digital. There is no quality loss in the conversion (inside the STB) from digital to analog, and no loss in the cabling. Yes it is true the Colossus re-encodes, but theoretically it is better than doing two re-encodes (digital -> analog in STB to go to component/composite/s-video, analog -> digital in capture card). mm [/QUOTE]
