#102 Mpeg files can't be played - codec needed
Taking a ty stream and converting it to mpg results in
an mpeg file that can't be played. I've tried all of
the combinations of output files as documented
(DVD/NoTrans, DVD/48, SVCD/44, Generic/NoTrans,
Elemental/NoTrans), yet none of these files result in
good mpeg files. To view I've tried on Mac OSX:
Quicktime Player (complains a software component can't
be found), Adobe Premire, iMovie, Windows Media Player.
On a Win2000 box: Windows Media Player (tries to
download a codec and fails). The ty stream plays fine
in tyeditor (OSX and PC). Below is a some of the
editor log.
What codec is ued for encoding? How do I get this into
Quicktime or Win Media Player?
Thanks
Matt

BTW, On the Mac OSX an the Tivo I am using 0.5b2. On the PC
I am using 0.5.

I have the identical problem. Matt, please email me if you
find out or have found a solution for this. Thanks.

It's a standard MPEG 2 file. You need to get a valid MPEG2
player
like Mplayer, VLC, etc
or buy Quicktime Pro and the MPEG-2 playback component,
$30 and $20 respectively from the apple store.

its my understanding that the sequence headers in the tivo
mpeg2 streams are a bit borked up... they may be "standard"
but what's in the headers is confusing to Quicktime.
see here:
http://www.videohelp.com/forum/viewtopic.php?t=216606&highlight=tivo
also:
http://homepage.mac.com/rnc/EditMpegHeaderIFO.html
apparently there are 2 things you have to change in at least
the first sequence header to get Quicktime to like the file.
first is that the stream has to be called out as being
720x480, 4:3 aspect ratio at 29.97 frames per second. the
second is that it needs to have a sane bitrate called out in
the header; the tivo files are all marked with 100mbit/sec
(rate=0x3FFFF, where 0x1 = 400 bits/sec)
if you fix these in the first sequence header, then
apparently at least DVD studio pro can parse the file,
ignoring the rest of the borked sequence headers and
apparently figuring out the true bitrate of the file.
i have not tried this yet because i am still waiting for my
CacheCard+Ethernet to arrive, but this is what i've been
able to glean from google and dvdrhelp.com over the past
couple of days.
