Limits
Starting point: RMVB - RMVB adds variable bitrate to the RealMedia container for smaller downloads. Variable-bitrate seeking can drift; verify sync after conversion. Rip sector headers first; raw sector dumps may fail to open. Encode DAT (MPEG-2 / MP2) from RMVB at a bitrate near the source, and confirm the audio track before converting.
