CorePlayer Mobile has support for the h.264 video codec (which is used by Apple for iTunes and hardware). Commercial codecs require a licensing fee. That is why CorePlayer costs money and TCPMP is free.

1. Use AnyDVD to break the encryption on your DVD.
2. Use Handbrake to convert the DVD to iPod low res video.
3. Import the resulting file into iTunes or copy to your device.
Note: I do this only with DVDs I own (fair use and all) and I never share my files (screw you MPAA).

Maybe it's just me, but I Use WMP For MP3's Only.. and TCPMP For Everything else.
TCPMP is nothing short of fully functional and fully stable for me. I tried Coreplayer for a couple of weeks and then got rid of it. It was slow on the GUI and hung many times playing diff types of videos. I'll stick with the not as pretty TCPMP.

Um... just in case I missed anyone else posting this (don't flame me if you knew this already):

TCPMP = The Core Pocket Media Player.

Think of TCPMP as a beta "prequel" to CorePlayer. TCPMP evolved through a number of betas and once refined was given a shiny new GUI and released for sale as CorePlayer.

"While TCPMP (The Core Pocket Media Player) is a terrific application, it never really had the slick, contemporary user interface (GUI) that most Palm apps have these days, and most of the features of the application are a bit too technical for the average Joe or Jane. It's still available if you want it but if you yearn for a little less geekiness, more features, and a prettier interface, you might want to take a serious look at its new commercial reincarnation: CorePlayer.

CorePlayer ("CP") improves on TCPMP by adding a shiny new GUI, which is customizable through various skin plug-ins, and better control buttons. It still has the VCR-style controls that its predecessor had, but CP’s buttons are repositioned and enlarged a tad to make them more fingerable."

Note: I have TCPMP myself... never tried CorePlayer personally.

i was trying to ask can u run TCPMP together with COREPLAYER on the 6800? i saw a video on youtube with a guy using COREPLAYER to stream live radio stations from shoutcast.com but i use TCPMP for my youtube any suggestions?

Re: CorePlayer Mobile & TCPMP
 

well the main reason you want to keep TCPMP would be the AC3 codec. If you do not wacth videos with AC3 sound, than take the CorePlayer (version 1.2.6 at least) it wil do as well as the TCPMP.
now there are a lot of differences between them but it is on you to decide.
let resume by it depends on what you use your player for and on what you expect from it. than compare and you'll have your ideal player ;)
