Converting MPEG1 files to MPEG4

			I stumbled across this app: http://www.geekshop.be/rien/file2divx3pass/... but I guess it's only for Linux so I'm looking for a good way to convert some of my MPEG1 files to xvid to save some room. (Need to fit an entire season of 70s Show on a single DVDR to be exact). I tried using VirtualDub, but the file size was still too big and audio sync got thrown off. Tried using Vegas DVD to use the MPEGs on a DVD and then use DVD-Decrypter/AutoGK to convert them, but still got bad audio sync. Any ideas?

			You won't really save any significant amount going from mpeg1 to mpeg4. Unless the original mpeg1 videos were at high res and not 320x240. You can save alot more but the quality will suffer quickly. Mpeg4 was really designed for high resolution low bitrate applications and doesn't do to good with low res stuff.

			oh well stink although that still doesn't explain the audio sync problem

			Audio sync issues can usually be corrected in vdub. At this stage I would generally recommend VirtualDubMod as an outright replacement to VirtualDub, but for your purposes it shouldn't matter. You can probably gain a decent amount of space, but your quality is going to be at best slightly worse than the original. If you choose to save very little space, you won't lose any significant quality, but then why go through all the trouble? At least your audio shouldn't degrade appreciably. I don't usually bother converting my mpeg files, but rather track down better replacements whenever possible.
