Vic's output bit rate is variable pending upon how different is each frame. You need to get a P166 or higher to crank up the bit rate and frame rate. vic is very , very CPU intensive. I have seen 2mbit/sec output rate when trying to output a severely distorted picture on a P166. Don't try to get a Pentium Pro 200mhz with a meteor working because the meteor has a hardware bug which will crash solidly the Pentium Pro. This has to deal with a PCI incompatibility between PCI 2.1 and the Philips SAA7116.
