I am looking for Batch Video Conversion software for my Creative ZV:M that is Fast, Reliable and Simple to Use???

I have an MCE 2005 PC so I need to convert Recorded TV DVR-MS files into XviD 5 (720-640x480, MP3, <2500 Bandwidth??). I would like to also convert some MOV, MPG, WMV, DivX3 and Non-MP3 Xvid files into the afore mentioned specs.

There are some files that also need to be joined together into one complete file. Can conversion software do this, or is an editing package required?

Is www.divmm.com Video Vault any good? (RedChair, PocketDivX, AutoGK, TMPGenc, ConvertX, etc...)

Thanks!
