    Hi,
    looking for some advice. Got hold of a 720p BluRay rip which I wanted to turn into a AVCHD disk. Followed the guide on here using TXMuxer et al and produced a disk on a dual layer DVD about 5gb in size.
    Drilled down to check the m2ts video stream was there and decoded ok on the PC - no issues (I've added the UDF 2.5 driver to my Win XP setup). So then I tried playback on my Panny BD-35 player... plays fine, chapters et al except there's no video shown, only audio. Ran BDInfo and all seems ok. Shows the playlist and m2ts file @ about 1h35mins and also MPEG 4 Video stream with a 3.1 profile 23.976fps
    Also Dolby Dig AC3 audio track @640k and presentation graphics marked as 'english'. Only thing of note was that 'language' was unset for the MPEG 4 stream (blank) and AC3 track language was labelled as 'undetermined' by BDInfo... not really sure what I've done wrong so if anyone has any ideas I'd welcome them. Even tho dual layer DVD media are reasonably priced i would rather not make a dozen 'coasters' before getting the settings correct.

    Hoping someone can point to something obvious...

    Hoping my nect AVCHD disk has a better outcome.

    thanks in advance.

    Bob.

    OK, this could be either one of two issues.

    1. The video stream itself is incompatible, er, encoded out of BD spec. Did you encode the video yourself, is is proper resolution... exactly 1280x720?

    2. The Panny BD35 is extremely picky on what "AVCHD" content it will play. Here is a link for more information.

    That link is to post 28, probably what you need to read. You should also follow along for more information.

    thanks Odin, that's all extremely useful info. I just updated to tsmuxer 188b and remuxed my source and then i did note the res was

    not 720 but 544

    SmartLabs tsMuxeR. Version 1.8.8(b) http://www.smlabs.net
    Decoding H264 stream (track 1): Profile: High@3.1 Resolution: 1280:544p Frame rate: 23.976
    H.264 muxing fps not set. Get fps from stream.
    H264 bitstream changed: insert nal unit delimiters
    H264 bitstream changed: insert pict timing and buffering period SEI units
    Decoding AC3 stream (track 2): Bitrate: 640Kbps Sample Rate: 48KHz Channels: 6
    B-pyramid level 1 detected. Shift DTS to 2 frames
    H264 bitstream changed: insert SPS/PPS units
    Decoding PGS stream (track 3): Resolution: 1280:544 Frame rate: 23.976
    Processed 138028 video frames
    Creation of Blu-ray playlist
    Creation of Blu-ray stream info and seek index
    Mux successful complete.
    Muxing time: 2 min 3 sec

    so that may be my issue as well. Guess I need to figure out how to make this back into a proper 720... more searching i guess :-(

    thanks for the info so far tho :->

    regards,
    Bob.

    Glad I could help. The only way to make this work is to recode your video to proper resolution (add the black widescreen bars). It's an extremely time consuming process, that's if you have a loaded PC.

    Here's a good start, there is a guide and applications bundled in to one download at the very beginning of the thread.

    I'd discovered RipBot which I'm currently using to put back the bars and return the res back to 720 instead of 522..

    sadly I've run out of dual layer dvdr to test it on. I am picking up some BDRE disks tomorrow which I assume I can author as AVCHD format so I guess i can test the resulting output with them till i get some more dual layer disks at the weekend. At least they can be re-written.. Still the cheaper option till BDR's come down a little in price.

    thanks again. Your posts saved a lot a trawling around :)

    regards,

    If you have a Blu-ray burner, here's something for you... if you're in Canada. I bought one, it works great.

    Dual layer (50GB) BD-RE.

    Man,
    that is seriously cheap! Sadly I'm in the UK. But given the price of media here it may be worth importing. I'll do some more checking...

    I bought 10 x BDR single layer riteks for about £35 so about £3.50 each and I've got a couple of 25GB BD-RE disks coming in the post soon as well at about £4 each. $20CAD is about £11 UK which is pretty good and being BDRE obviously its reusable.. certainly not seen BDRE 50GB here yet and certainly not at that price.

    thanks for the tip :)

    cheers.

    What you're paying for blank BDs is pretty much the same over here. Hopefully you'll see D/L BD-REs cheap soon.

    Hi,
    just wanted to say thanks for all the assist. Finally got the recode done of my 720p d/loaded source and burned it to my BD-RE - works like a charm. Now attempting a larger 1080p source !

    I guess the next experiments will be how much I can squeeze down a 720 or 1080 source to a single layer DVD without losing too much quality!

    Plenty more to learn!

    thanks.

    Good to hear everything worked out. If you are going to attempt 1080p files, I suggest DVD9s.
