Hi,
I can confirm that Xilisoft's "DVD to MP4 converter" works perfectly with both 220(224)x176 and 320x240 Rockchip MP4 players. I purchased this over the weekend and it's worth every $.
I was also able to succeed with the 'free-issue' AviConverter which came with each player once I worked out that I need to manually put .avi at the end of your filenames , but I REALLY like the flexibility that the Xilisoft software gives you.
For example, instead of coding each of the 4 or 5 VOB files individually one after the other (as with AviConverter), the Xilisoft DVD to MP4 software does it all in one go, straight from analysing the IFO's. It can convert straight from DVD - and it appears to work straight from an original DVD ( Region 2 - I cannot confirm this for other regions).
I know I am repeating what others have written above, but to confirm what has worked for me, I use the following settings:
For the 2" player (224x176) :
First, select 'XviD' as the Profile.
For Video Size, manually type "224x176" - on my version (4.0.83 build 0178) this size doesn't appear in the drop-down, but manually typing it as I have shown here, works.
Bit Rate - I have found that 512 works 100%.
Frame Rate - at 20FPS, the sound and video remain in sync. Higher FPS ratings result in a slightly smoother video, but the sound lags behind.
Aspect - Auto
Same Quality - False
Audio Codec -
MP2 -
Important Note! Although Rockchip players handle MP3 Music fantastically, the video audio must be encoded as MP2 it seems. Xilisost are one of the only ppl who seem to realise this!!
Bit Rate - 128 works for me everytime.
Sample Rate - 44100 - ditto!
Channels - Stereo
Disable Audio - False
For the 2.4" Rockchip players, do exactly as above, but select a video size of "320x240"
The link for the software is
http://www.xilisoft.com/dvd-to-mp4-suite.html - What's great, is you can download a free trial version which seems to do everything other than it limits your converting to 5 minutes per file. It's well worth trying this out before parting with your $$$, but for me, it has worked very well indeed.
Good luck, and I hope everyone who's been stuck on this now succeeds! Rockchip players are fantastic value - anyone know if there's a 2.4" version with a removal 'cellphone/mobile' battery on the market yet?
