AVG Antivirus updates have a ".bin" filetype - on systems where AVG is installed, this causes confusion with the CUE + BIN CD Image format.
The CUE describes the data, format and track details
The BIN contains the data
If it's a BIN/CUE of video, it's probably in (S)VCD format, so burn it as a "Burn from Image file", in anything that understands CUE/BIN (burnatonce is probably the best at this - Nero can, but some say it doesn't support ALL CUE features).
I'm surprised WinISO isn't doing anything useful with it?
