In AGK, you can target File size & set it to 5MB for a 2 minute video, and keep a fixed width of 384(VCD Standard) & let it choose its own audio or choose VBR mp3 @ 64/96kbps.........additionally you can access hidden settings by pressing Ctrl+F9...Frankly speaking, for transcoding, video captured via TV tuner, use VirtualDub MPEG2 with VP70 & DivX WMA V2

Th reason why u remove the black bars: when u have black bars, it creates a high contrast region between the black & picture areas wher ul end up wasting bits.....if u remove it, the bits will be used more effectively in the picture frame only........the final filesize discrepency is not due to the filter u selected but due to incosistensies in the codec, as u r using one pass...
@runeet
There is a solution.....to have good quality @ high res u will have to use a powerful codec like VP70 @ at least 500-1000kbps in Virtual Dub.......in the video filters use, "presise bicubic A=1" in the resize filter.........if u wanna increase the resolution to a very high one, u will have to do the entire encoding 2 or three times.......
eg. 160x120 -> 384x288 -> 640x480. If u directly do, 160x120 to 640x480, it will give u really bad results......
