Latest Tivo Stream 4k firmware update

Post by GGRussell »

Updated my Tivo Stream 4k this morning and proceeded to watch Olympic recordings. Was unwatchable. Very jittery video but audio seemed to be fine. IF I FF or RW, jitter will stop for a second or two and start again. So I tried other recordings. All were the same. Suggestions?

Can confirm on my STREAM 4K. What's odd is that it will play fine if you stop playback and then resume it, but the moment one skips back or forward, it goes stuttery. I will make sure dev team knows about this.

Not sure what has changed, but the stuttering has stopped this evening. So far anyway... Will be catching up on some recordings tomorrow

Severe Stuttering is back on recording playback this morning. Doesn't matter which channel. Hopefully we can get an update soon to address this issue.

I am still experiencing occasional severe stutter on my Tivo Stream 4K device on playback of recordings. Makes watching difficult.

Any update on this? Makes watching the Olympics very uncomfortable. The stuttering doesn't stop even if I watch for hours. FF or RW doesn't help any more either.

I set up a Tivo 4K Stream dongle here.

I see a little bit of stuttering when the channel starts but it is right within a few seconds.

Interestingly, it looks like TiVo has fixed the previously-broken MPEG2 hardware support. We will re-enable hardware MPEG2 support on this dongle.

Running more tests.

A few notes from my testing...

1) The TiVo Stream 4K is decoding 1080i and 480i channels at 29.97 frames per second, possibly by doing field drop. The quality is not very good on 1080i or 480i channels. 720p channels are fine.

2) The TiVo Stream 4K seems to only support running the HDMI at 60fps and doesn't give the app the option to switch to 59.94fps like most Android devices.

3) The TiVo Stream 4K seems to be miss-reporting the audio output delay and doesn't have an obvious way to manually correct it.

I was able to reproduce a stutter when first starting a channel and using AC3 passthrough. This has been fixed.

It will take the day to complete QA and hopefully be released tomorrow.

I have two Tiveo devices. One is connected to LG OLED 4k. The Tivo recognizes it as 4k HDR @60
The second is an older LG 1080p. I get stutter on both.

Just installed 20210728 and so far seems to be better. Will record more Olympics and watch later. Then report back. Thanks
