>>I have to concur. The correct choice of video compression coupled with the proper output resllution make all the difference.<< I totally agree w/you. The problem that William described matches a problem that I had. I wasn't trashing MSV1, just trying to help. The disk file (AVI) is ok, but there is some interaction between the 64k driver (on my board, and his too, it seems) and the MSV1 decompressor. I cannot isolate the problem. Sometimes it works, sometimes it doesn't The problem does not occur in any other color depth when playing the same AVI. This is a VfW problem, not an ER problem. I think you misunderstood my message. >>160×120 or 320×240 and all the compressors should work ok but many of them will choke on 640×480 or bizzare resloutions like 423×278 (or whatever).<< Indeo 3.2 doesn't like large files. The rest of the codecs don't seem to mind them. As long as your output res. values are divisible by 20 (160×120, 320×240, 400×300, 800×600, etc), there shouldn't be a crash problem, according to Microsoft and my own personal experience. I still think the Cinepak codec offers the best combo of speed/quality/file size, as long as you keep the quality setting at 100% and use a high data rate. MSV1 can achieve excellent quality, as long as you don't mind relatively (sp?) large files. Sorry to ramble. Keep up the great work, and long live ER! Rob
