I recently purchased a Chromecast with Google TV HD to replace a SmartVu SV10 dongle which had died. However, the performance of the HDHomeRun app (using a Connect - HDHR4-2DT(AU)) on the CCwGTV is terrible, with lots of jerky pictures. When initially selecting a channel in HDHomeRun, it starts off okay but within a couple of seconds it deteriorates - this is across all channels. No other apps on the CCwGTV appear to be affected and I've confirmed via Stats for Nerds that a 1080 Youtube video plays without any dropped frames.

I grabbed a MiBox 3 from elsewhere and tried the HDHomeRun app on that. No issues whatsoever. Surely the HD version of CCwGTV should be able to deal with the output from a HDHomeRun?

Have you considered frame rate as a possible factor?

NZ TV is going to be 25fps, but Android devices were (at least in the past), fixed at 60Hz.

The 'output' from the HDHomeRun is just a MPEG transport stream that the player must decode and display. If you have a media player that can stream directly from the HDHomeRun via HTTP, you could try that and see if it looks any better.

I guess I didn't make it clear that the HDHomeRun Android TV app works fine on the MiBox3 I subsequently tested with. The HDHomerun app on my Android phone and its predecessor also works fine. It's only the HDHomeRun app on the Chromecast with Google TV that is having an issue.

Yeah i think I've found that as well. Where I use the apple tv hdhomerun app and it's fine.

I think the stream might be too much for it's little processor. I think I ended up using plex or live tv via tvnz app.

An update on this. Family member wanted a Chromecast with Google TV, so sold them my HD one and purchased the 4K model. HDHomeRun works just fine with the 4K model, with no picture pauses - so yes it would appear that the HD model is a bit underpowered.
