Bugs in TMPGenc & Elecard...

It seems I've found a bug in TMPGenc...
I was trying to encode the latest Charmed for me wifey, and I set up
TMPGenc to encode the show 2-pass VBR with the settings:
Average bitrate: 2355 Kbit
Maximum Bitrate: 2474 Kbit
Minimum Bitrate: 300 Kbit
and I tell TMPGenc to record all logs on the processes - most folks
would think it's boring, but I *am* a packrat, remember??? ;-)
Anywho, I wrote a small perl program to snag the Min & Max bitrates
that TMPGenc encoded with, and this is my command-line & it's output
for TMPGenc Version 2.52:::::::
C:\!Tivo>cat Charmed_CharmedAndDangerous?*.log|grep "^Current"|gawk
"{print $4}"|perl calc.pl
Max: 4336.84
Min: 663.23
::::::And here's the output for TMPGenc 2.51:::::::
C:\!Tivo>cat Charmed_CharmedAndDangerous?*.log|grep "^Current"|gawk
"{print $4}"|perl calc.pl
Max: 4436.42
Min: 663.18
::::::
No wonder they wouldn't fit on the CD... Anywho, I guess I'll try
encoding CBR this time just to get the job done; and keep an eye on
this in the future. :-/
BTW, for those who remember, I run Win2K for my encoding... so y'all
might be asking: grep? gawk? What the... ;-)
As I've said before: Cygwin is your *friend*... ;^>
Also, I've found that when playing back MPEG2s using the Elecard
decoder, starting up the first MPEG2 makes the video *very* dark,
then the 2nd and subsequent videos opened at the same time will have
normal color. I found this bug while trying to see the difference
between encoding with 8/9/10 bit DC component precision & changing
some settings under the "quantize matrix" tab... It's too bad - on my
system, it was the most crash-proof encoder I tried. Back to the
drawing board... :-/
Well, I'm off to fix a batch encode; running low on HD space & I have
a bit of catching up to do... Laterz,
Roger "Merch" Merchberger
