- The MPEG viewer is a terribly written program. I practically NEVER
- yields. It takes several tries to get clicks on the "stop" button
- to register. However, it has to be this way because it has alot of
- work to do to get 15 frames/sec on an ET4000. It uses a special
- DLL to access the video directly, bypassing windows.
-
- However, since Windows runs all windows programs as one pre-empted task,
- and each dos program as its own pre-empted task, my DOS comm program
- was able to keep downloading full tilt while the mpeg movie ran.
-
- I don't follow what you mean by saying dos boxes give windows serious
- problems. As far as I can tell, the only really serious problems windows
- has is with accessing floppies.
-
- Also, for those of you who say that windows can't run dos stuff well
- except benchmarks:
-
- Using free jpeg source compiled with Intel CodeBuilder (32-bit DPMI)
- doing jpg->gif on a 272x400 color jpeg file:
-
- Plain dos : 14.61 seconds
- Dos under win 3.1 : 14.72 seconds
-
- I want to mention that I am a home/hobbiest user of my PC, and have
- not tried any of the acane things that windows is not supposed to be
- able to do, such as run two instances of the same comm package at
- the same time on two different modems. Also, I rarely use floppies,
- mainly just install applications and do small incremental backups of
- data. If my life revolved around floppies, I'd probalby hate windows
- and love OS/2.
