I have encoded videos for my HTC Desire in MP4 format using these settings, H.264/AVC Codec, AAC LC Audio, 800 x 480 res, 23.976fps, 960kbps video, 32000 audio sampling frequency, 2 audio channels, 96kbps sound, It worked fine for my half hour videos on my phone which came to 500mb but I have just converted an 11gig 2 and a half hour video to a 2.4 gig video using the exact same settings, the video is fine on my PC but refuses to play on the phonw, any ideas?
