    Has anyone used the HDMI Mirroring to their TV? My television tells me that the audio output from the phone is in a bad format. It still plays sound from netflix and video is fine but the sound quality is poor with occasional crackles/hisses and some synchronization issues.

    What brand of television?

    I'm going to try with a different when I get home from work. If problem persists I'll take the cable to Verizon store and exchange.

    Do you need the webtop dock thing in order to do it or can you go straight from the phone to the TV? I haven't tried it obviously but I was just curious if the dock was required.

    There is a cable so you can go right from the phone to the tv. When you plug it in the phone asks if you want to start mirroring.

    I believe the occasional crackling with Netflix over HDMI is a known issue. My wife and I both have this issue with our Bionics, and I've seen it mentioned in the forums as well. I can stream Google Music beta over HDMI with no crackling, and Netflix doesn't crackle when played through the phone speaker, so it seems to be a weird bug with just this combination (Netflix + HDMI). Not sure if we need a Netflix update to fix it or what. I also ordered a longer HDMI cable, so I can test that when it arrives to completely rule out a faulty cable.

    Has anyone figured out a work around for NFL Mobile app yet. It would be awesome to watch on the big screen, even if it was a bit pixelated

    I don't get any crackling, but playing Netflix via HDMI mirroring is extremely choppy - too annoying to watch. When I watch Netflix straight from the phone I get excellent playback and quality.

    As Somniferum says, "it seems to be a weird bug with just this combination (Netflix + HDMI)". I really hope they fix this issue as the Netflix option was a significant decision point in my purchase of the Bionic.

    It must be the TV. I connected to my "generic" brand LCD and everything works great. So I guess the lesson is high-end TV's suck for HDMI mirroring.

    Netflix was still a bit choppy though. Streaming stuff from my computer using zumocast worked great.

    Tested hdmi cable only to TV and also to a projector and both work fine.

    I registered here just to quote this. My biggest gripe with this phone and HD dock.
    I have a bunch of blue ray backups encoded at 720p and none of them play back for crap. All sorts of choppiness and it's not even viewable. Wouldn't you think a phone that records '1080p' could at least play back 720?

    No.

    I've reproduced the same problem on my 'high-end' living room TV and my bedroom (not so high-end) TV.

    I wonder if the app "Act 1 Video Player" would work for playback.

    I know for a FACT, that the software "DVD Catalyst 4" can and will CONVERT videos that can play in HD on the Droid Bionic. It only cost me $10. Here is their website: http://www.tools4movies.com/

    I installed MX video player and the playback was the same. It appears to be some sort of hardware limitation:(

    With most Android devices, its not that 720p is the limitation, but some of the advanced settings used to encode the video to H264. Things like the profile (main, baseline, high) as well as Cabac, Reference frames etc are not supported fully, so you end up with either unplayable files or stuttering playback. Of course, the audio format from your files is also a big factor. 5.1 audio is problematic, and will either result in hissing or no audio at all.

    Players like Dice, Rock, Mobo can make those files play, however, because they use a software-based decoding engine, rather than the hardware, the processor speed as well as the optimizations used in their codecs become a major factor in playback as well.

    Thank you, I was just mentioning your software and how it works well for me. I appreciate your educated opinion on this.

    Bitrate is probably an issue too. Not sure what the phone can handle for playback.

    I am not sure about the Bionic, but on a Xoom I stopped at 20Mbps H264 (1080). On my Droid X and my NOOKcolor, I think I stopped at 5000Kbps. In all cases the video played back fluently, so I would expect the Bionic to be able to handle 5000 easily.

    Edit:
    The 1GHz TI OMAP 4430 seems to be in the Playbook as well, and on that I also managed to play a 1080 video at 20Mbps

    Yep. Still 5mpbs should be no problem even for mp4 decoding.

    I think the issues are in the HDMI conversion... even still photos look washed out & grainy.
