I have had my R4i-SDHC v1.4 card for a long time with moonshell and everything was fine. Until I got a brand new DANE-ELEC MicroSD High Speed 8GB. So to celebrate I decided to convert, like, 25 videos to put on the card. So I got all the videos I wanted and converted them with Xilisoft Video Converter Ultimate 6, like I always have, to DPG4. After I converted them all, I put them on my card and now when I play the video it pause for a split second or two in the middle of watching it and then speeds the video up to catch up to the audio causing it to go in an endless cycle of a second pause, speed up, slow down and repeat. Only about half videos worked and here are their specs. First Video Length: 00:02:22 Frame Width: 320 Frame Height: 240 Data Rate: 55kbps Total Bit Rate: 180kbps Frame Rate: 11 frames/second Second Video Length: 00:02:04 Frame Width: 320 Frame Height: 240 Data Rate: 289kbps Total Bit Rate: 415kbps Frame Rate: 12 frames/second And last here are the specs of one that didn't work. Bad Video Length: 00:03:43 Frame Width: 320 Frame Height: 240 Data Rate: 199kbps Total Bit Rate: 323kbps Frame Rate: 9 frames/second I think that it might be the frames/second that's the issue. What do you think? I found the only ones that worked are ones that are 11 frames/second or 12 frames/second.
