I've recently started learning how to extract the data off my Tivo, and reincode it into SVCDs for archiving purposes.
After cutting the commericals, the total run-time is usually a little bit under 45 minutes, but just to put some extra-care buffering in, I use 45 minutes in the bitrate calculators. The audio bitrate is 192 kbps.
The bitrate calc here on VCDHelp.com gives me a result of avg 2213, max 2528 in order to fit 45 minutes on a single 80 minute CD.
According to FitCD 0.9.9, 45 minutes of 480x480 SVCD in 6 mpeg tracks, 29.97 fps, multiplexed with TMPGEnc, and burned with Nero 5.5, the calculated bitrates are avg 2232, max 2552.
As a consequence, I ran it overnight encoding it at avg 2180, max 2525, just to be absolutely sure. I stick the 6 mpegs into Nero, and it works out to 84 minutes of CD, and won't burn. This is despite my undercalculation of bitrate, and the fact that the edited chunks actually add up to only 42 minutes and 11 seconds.
Even stranger, I downloaded BitrateViewer and checked the pieces. They all actually average 2060, which is even lower than my underestimation.
In short, everything shows that this stuff should fit on a single 80-minute SVCD with room to spare, but instead I'm too big to fit. What gives?
Thanks in advance

Havent used the bitrate calc on here in awihle..I took a glance at it, it looks different now though..anyhow, I use a different calculator..and it reports that you avg rate for 45 mins of video with 192 bps audio should be 1937..not 2200 something...in order to fit on a 80 min CD...Ive use it for awhile now, so I know its accurate, maybe the calc on here got screwed a little somehow..try emailing Baldrick to let him know.

Can you tell me what calculator you're using? And where you got it?
TIA
