If you use a hardware mjpeg card, such as the Pinnacle dc10plus, cpu speed will not be as much as an issue, as the encoding is done on the card and not by the cpu. The MJPEGTOOLS utilities can convert these streams to a number of format, including DivX, which is highly compressed and would allow you to store more files on the disk. I don't know if the ATI All in Wonder cards have much linux support, at least I did not see anything. I use the dc10plus and the quality is pretty good. My ATI AIW has Macrovision protection on it, and I'm pretty sure it is hardware based, but cannot tell you for sure. That really upset me after paying $200 for it several years ago, with the express purpose of saving some old worn videos my kids like to watch over and over again. I would recommend staying with as mainstream of video card as possible, those using the ATI Rage or nVidia chipsets, those are well supported, but I can't recommend a specific model for video out. thats my 2 cents worth.... ---------- Original Message ---------------------------------- From: Kevin Atkinson <kevin@xxxxxxxxxxxxxxxx> Reply-To: video4linux-list@xxxxxxxxxx Date: Wed, 23 Jan 2002 09:49:06 -0500 (EST) >I already posted this to livid-user but that list doesn't seam very active >so I decided to repost it here. > >I would like to start a project and/or work with existing project such >home-brewed TiVO system for two main reasons 1) for the fun of it and 2) >to make a statement to the RIAA and the MPAA that they are not going to be >able to control the flow of information period.
