I have three standalone DVD players. 2 are realitively new 7" portable el-cheapos bought at a discount store. One is a Phillips combo DVD/VCR player (DVP-3050V) I've had for about 3 years. A very few converted .AVIs-to-DVDs have completely rotten audio but OK video on the Phillips. Stangely enough the same DVDs are perfectly OK (video and audio) on the two cheapies. I'm using Nero Vision V4 and ConvertXtoDVD on my XP Pro machine with a Lite-On DVD Multi-Format writer. Since I can't figure out what's going on my questions are: Is this a media problem? Is this a codec problem in the computer or conversion software? Is this a problem with my DVD R/W drive? Is the Phillips stand-alone long past it's replacement period (and I just have to live with it)? Is there any way to tell in advance if a particular AVI is going to run into audio-conversion problems (so I don't bother with it rather than spend time in trial and error)? Thank you, all!
