Playback of file causes appletv to reboot

Question

i converted a whole batch of tv episodes, all converted using the same program and the same preset.
they are all a 4:3 ratio and were converted from DVD.
now, it appears that some have a resolution of 788x576 and some are 788x592.
now, for some reason some of the files play fine, however other seem to make the appletv reboot.
i can't seem to work out what is causing this. not sure if it is the conversion or whether it is something that metax has done to the file.
here are the details of one of the files causes a reboot
format : JVT/AVC coding, 720x592 (788x592), Millions AAC Stereo (LR) 48000KHz
FPS : 25
Data Size : 256MB
Data Rate : 1512 kbits/s
normal size : 788x592
current size : 788x592 (actual)
appletv is unmodified and has actually had a factory restore today (for no specific reason other than to clear some "stuck" podcast favourites).

Answer 1

I couldn't be sure if it relates to your problem but there is something wrong with your dimensions. DVD (PAL) is 720 x 576 (encoded pixels). For 4:3 content the display size should be 768 x 576.
Increasing the number of encoded pixels during conversion is an extraneous exercise since you cannot gain quality and merely increase the amount of space the file occupies or more likely increase the amount of compression required to maintain the same datarate.
That being said, increasing the number of encoded pixels shouldn't actually be a reason in itself to cause you playback issues as you describe them. However, it should be noted that the software I suspect you have used doesn't ordinarily increase the encoded pixels, so one has to wonder if something isn't going wrong during the conversion stage.
