Advertisements Issue is now fixed. See my 7-30-15 update at the bottom of this post. Please see this post if you would like to submit this bug to Tivo support. When I upgraded from a Tivo S3 to a Roamio Pro and Mini, I noticed a visible reduction in image quality. Many of my 1080i channels looked soft and blurry compared to the crisp output from the old S3. Doing some investigation with an HDMI video capture card, I figure out what was happening. The Roamio and Mini are incorrectly inverting the top/bottom fields of an interlaced 1080i signal or doing some kind of additional image processing. Here are some examples of what I'm seeing. 1080i output captured from Penny Dreadful credits on SHO. All Images below were captured from running video. Tivos were NOT paused or slowed down. Based on feedback in this thread, the Tivo Premiere does not have this bug. It is Series 5 only. Zoomed Tivo Mini on top. Zoomed Tivo S3 on bottom: Original Mini frame: Original Tivo S3 frame: When you look at thin horizontal edges at the top/bottom of the letters, you see that they are flipped vertically. If you were to swap them, you would end up with the same clean image as the S3. I've seen this problem from many of my FIOS 1080i channels. Example is from 870 SHO2PHD. Also seen on 600 CNNHD and others. If anyone would like to reproduce this problem or has any engineering contacts at Tivo, I have uploaded a sample recording that you can transfer back to your DVR using Tivo Desktop software: http://www.filedropper.com/sho2phdcredits2 (Click "Download This File") Mirror: https://www.sendspace.com/file/ny3jgy ("Click here to start download from sendspace") Be sure to set your Tivo output to 1080i. The issue is harder to see in 1080p or 720p. Update 7-11-15: I captured some CBS from my rooftop antenna to make sure this was not some issue with my cable TV provider. Same problem. Old Tivo S3 and PC display image correctly. Tivo Roamio Pro and Mini flip the fields: Clip from the recording that you can transfer to your Tivo using Tivo Desktop software or play on your PC: https://www.sendspace.com/file/kub1fs ("Click here to start download from sendspace") Update 7-11-15: I tested Roamio set to 1080p output. This ends up flickering between 2 images, neither of which looks correct. This flipping between the 2 images happens 60 times per second so you may not notice it. In any case, it's clear that both 1080p images look inferior to the sharp output of the S3. Update 7-12-15: Tested H.264 1080i channels on FIOS and saw the same inverted field problem. The bug is not specific to MPEG2 and seems to affect all 1080i channels. Content encoded in 1080/24p or 720p does not show the bug. Update 7-15-15: Recorded NBC from Los Angeles station KNBC using over-the-air antenna on S3 Tivo and transferred to Roamio for comparison. Small sample from the disclaimer text at the end of a car commercial: Clip from the recording that you can transfer to your Tivo using Tivo Desktop software or play on your PC: https://www.sendspace.com/file/0cfrv2 ("Click here to start download from sendspace") Update 7-15-15: Sample of commercial from CNN Channel 600 on FIOS. This commercial was filmed with progressive camera @29.97 fps so both fields of each frame are from the same instant in time. As a result, when you step through the original file you will see that none of the frames are interlaced and show no combing. There are no repeat-first-field flags present so nothing should be re-interlacing these frames. When I step through the frames captured from Tivo S3 HDMI, they look exactly the same as the source file - no combing. When I step through the frames captured on the Roamio or Mini, they are all interlaced. This is clearly incorrect decoding of the source file. Note: These screen shots show what is being sent out of each Tivo. Since your TV will automatically de-interlace the video, you won't see the combing like I've shown here. The point is that this sample should not be interlaced to begin with. Both Tivos should output exactly the same image before it enters your TV. http://www.filedropper.com/cnnfios (Click "Download This File") Mirror: https://www.sendspace.com/file/gy2bsk ("Click here to start download from sendspace") Update 7-20-15: Updated download links for some of the missing sample files. Please send PM if you find any dead links. Update 7-30-15: My Roamio Pro received an automatic software update to 20.5.2-USA-6-840 last night. Upon reboot I quickly tested all my samples. Bug is definitely fixed!!! Also tested my Mini with update to 20.5.2-01-6-A92 and it's also fixed. Results are indistinguishable from the old Tivo S3 when playing 1080i channels over HDMI.
