[ExtractStream] Re: Error in audio packet header!

[Don McAllister]

Thanks John, I have used Rogers guide before without much success but I
thought I’d give it another go and perhaps document the problems.

Extracting the stream seems to be OK and I end up with a .ty file on my
PC. However, when trying to split the file as per Rogers instructions
the following happens:

Followed http://www.30below.com/%7ezmerch/tivo/ ti the letter.

All software downloaded via links on the page.

NB This is a UK 2.5.5 PAL Tivo

OS used = Windows 200 professional
Telnet Client = NetTerm 4.2.d.2

1st Attempt
Used Sendstream to extract (used -w 5) rooms.ty file = 818,176KB

zss.exe failed to run requiring .dll

zzs5nc.exe produced:
bad-rooms.ty 816,000K
rooms.log 5KB
rooms.m2a 96KB
rooms.m2v 1,931KB

rooms.log contains various errors for example

Lots of:
Warning: unknown record type 5 in chunk 1 record 0

A few:
Warning: unknown record type 4 in chunk 16 record 28
audio failure 30:0x360 0x20:0x20:0x20 chunk 16 last audio time
00:16:55.616 last video time 00:00:04.280
hmpf: audio sequence not 0x2D1C40 at chunk 17 record 27
last audio time 06:30:19488.367 last video time 05:15:16252.998


2nd Attempt

Used Sendstream to extract (used -w 3) rooms2.ty file = 818,176KB

zzs5nc.exe produced
bad-rooms2.ty 816,000K
rooms2.log 5KB
rooms2.m2a 96KB
rooms2.m2v 1,931KB

Error log same as before

Any Ideas?

Don

Hey, Don!

As Josh has pointed out earlier, the streams from TiVo are in 
"transport stream" format, whilst the streams most programs are 
expecting are in "presentation stream" format.  As Roger reminded you, 
use DVD2AVI to create a project, feeding the resulting *.d2v to 
TMPGEnc.  Again, you could do a lot worse than to follow Roger's 
comprehensive guide at http://www.30below.com/%7ezmerch/tivo/

That being said, TMPGEnc is an interesting program in that although in 
some respects it is EXPECTING raw transport data from a video capture 
card (look at some of the defaults it has, particularly "Field 
order"), yet it cannot accept the half-civilized video stream from 
TiVo.
