S370 discs jump at same time

[highlander317]

We have a BDP-S370 blu ray player and over the week or so have noticed that about the 1 hour 15 minutes mark the disc stops and then starts again. This has become more and more noticable. It happens on both original and homemade discs in dvd format.

Any help is appreciated

Cheers

Hi,

on normal dvd's this is down to what is known as layer change, basically what this means is that all pre-recorded dvd's have a dual layer surface to record apon and this "jump" is down to the player finding the second level.

now as for blank media doing this, this can only happen if you are using dual layer dvd's, these are 8.5GB, if you are using single layer (4.7GB), it wont do this.

all blu ray discs do not exibit this trait.

hope this helps.

If the problem is related to a specific disc only, that mean it has surface scratch / dust on the track recorded at 1hr 15min...the remedy will be clean the disc surface and slight polish it using a damp soft cotton cloth.

If the problem is related to many discs from different sources that mean hardware problem ( the laser lens carrier mechanism may stuck at a specific point).

May be this help.

Hi,

KDL-CX520

not entirely correct on the disc cleaning there unless you are referring to 45's or LP's, DVD's do not have grooves or tracks as the discs are completely smooth, the very best you can do is wipe off any fingerprints from the centre outwards

.

perhaps highlander317 can add if this happens on blu ray also as all that was mentioned was original and homemade discs in DVD format.

then your statement on a fault with the laser track may carry more weight:smileywink:

Have not noticed it happening on blu ray discs, only original dvd and backup dvds. All my backup dvds are single layer but understand the backed up movie may cross the layers from the original disc, but every movie I backup? seems odd to me.

Some of the jumps are quite harsh and when I explained to the wife that dvd cases used to have a warning written on them about the skip between layers was normal, this current problem is more than a skip and becoming more of a short pause.

highlander317,

thanks for clarifying that, something certainly is not normal here, may i suggest playing these on another player to rule out the player, if it does it on another player then its down to the dvd's,

i used to rip and copy hundreds of dvd's in the past with no problems like this.

granted we understand layer change but this sounds like a little more than that,

are you doing full back ups (8.5gb) or are you shrinking to fit 4.7gb?, this may be an invalid question as you have said you are experiencing this on normal DVD's.

please do try another DVD or blu ray player and see if the problem persists.

regards.

Usually just copy the main movie to backup not shrink the whole disc to single layer. Ill try a definate problem disc in another player and see what happens. Watch this space

[highlander317]

Just tried in the kids room and the original disc did not jump. going to try again on problem player when they go to bed to get the exact time of jump/skip and can try in another bedroom.

Have just tried on 2 other players both dvd and the jump is hardly noticable nothing like the blu ray player.

Anyone got any ideas?

Hi,

ok, presuming the other two players are DVD players then unless theres something amiss with the laser carrier in the blu ray player i do not believe theres much you can do about it,

unless im mistaken i read somewhere that the laser on blu ray players are a lot finer than the ones found in normal dvd players and it could be because of this you are noticing this "jump".

i have played a lot of dvd's in my s570 with no ill effect, yes you notice a layer change but rarely,

we could go on for days trying to come to a solution if there even is one, so my advice would be to get a service engineer to take a look at the laser to see if its snagging anywhere if you are that worried or you can just settle for playing dvd's in a dvd player.
