Deinterlacing quality of sports?

Channels Apple TV
#1

Hi, I’m interested in purchasing Channels but am cautious of the quality of playback of sports whilst deinterlacing.

In Australia we have a number of channels at 1080i and I’ve tried VLC for playback of this content and it’s built-in deinterlacing causes a lot of motion blur whilst waching sports, such as the Olympics.

Would love to hear feedback from current users on if they experience much motion blur with their Channels App deinterlacing? I’ve noticed there are now two settings for deinterlacing in the app as well.

@ozrex I just purchased channels & aTV to help me move away from Windows Media Center setup.

I’m in Melbourne, using a HD HomeRun Connect, happy to provide some feed-back.

I tried to watch a bit of AFL last night, and noticed possible interlacing issues (slight blurr and quite an odd visual artifacts in the green grass), but to be honest I was more upset with Hawthorn.

Anyway, let me know if I can help.

Our OTA channels in the US (ATSC) are MPEG-2 encoded. Only two of the major networks (ABC, FOX) broadcast HD in 720p and the others (NBC, CBS, PBS, CW) in 1080i. The aTV cannot play MPEG-2 natively so it is software transcoded in the Channels app to MPEG-4 (H.264). Here this is working very well for both 1080i and 720p broadcasts.

I just got the new HDHR Extend and it works just as well if I select “None” as the transcoder, but if I have the HDHR do transcoding it seems to be outputting interlaced H.264 on the 1080i channels. This results in choppy playback. The 720p channels work much better. Pretty sure this issue mostly lies in the HDHR firmware itself.
