I used this utility found here. I burned the program to disc, and put the AVI file on another CDR made with ps2cdgen. However it didn't work wo well. It would play, but it would like lag, it would stop for a second then start to play again, it would do this every ten or so seconds. Is there someway I can solve this? Or is it just that the porgram only works so well and it would be possible to get it to work?
Realityplayer has quite old codecs so those along with PS2's limited processing power causes that all movie files won't play perfectly: NewerDivx/Xvid options like Qpel and Packet Bitstream are serious poison for Realityplayer, and movies with high resolution and/or low compress factor will cause problems too. Try to lower color depth and picture quality from Realityplayer's setup, maybe it will help.
It somehow seems smarter to just make VCDs and DVDs. I mean, I have a DVD player which will play VCDs. I don't see the actual purpose of the media center, It just seems to make more to do the encoding process than to suffer with the laggy video.
I've watched many about 700 Mb made-for-fit-into-CD Divx/Xvid DVDrips with Realityplayer and most of them have worked fine, bigger HQ rips have been laggy or haven't worked at all but I'm still quite satisfied for the player. I have DVD player which eats everything round-shaped I'll feed for it, even AVI and MPG files, but I like to use PS2 for playback on the other room.
One important thing to prevent lagging and skiping is to use same media for movies that you normally use for your PS2 backups, I have noticed that when I burned some movies into DVD brand which my PS2 don't read very well as used in backup purposes the movies didn't work either: I got them to play but there were lots of issues in playback. Then I burned movies on Ritek G04 which I use for PS2 backups issues disappeared. That's quite logical since some PS2's are very sensitive about used media brands with games but that didn't came on my mind at the beginning.
