Hi all

I've been running MediaPortal 1.0.2 for some time now with "no" problems (is there ever an HTPC without at least a few minor issues?!?), but a couple of days ago something went wrong. My TV card is a 6 tuner device (2xDVB-S + 2xhybrid). I don't know what happened, but now I am not able to access the "property" page for one of the DVB-T tuners in TV Server config (under "TV Servers"). The entry still appears, but nothing appears to happen when you click on it. The error log for TV Server says an exception is being thrown:

2010-04-23 10:42:54.515625 [SetupTv]: Exception ystem.FormatException: Input string was not in a correct format.
at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
at SetupTv.Sections.CardDvbT.OnSectionActivated()
at SetupTv.SetupTvSettingsForm.ActivateSection(SectionSettings section)

All the other tuner pages can be accessed as per usual. Having said that, attempting to scan channels on the analog side of the same hybrid tuner mentioned above fails. TV Server config crashes with:

SetupTv has encountered a problem and needs to close. We are sorry for the inconvenience.

...and in the logs:

2010-04-23 10:44:36.171875 [14]: Exception :TvLibrary.TvExceptionSWEncoderMissing: No video compressor filter found. you must install a supported video encoder!

at TvLibrary.Implementations.Hybrid.HybridCard.Tune(Int32 subChannelId, IChannel channel)
at TvService.CardTuner.Tune(User& user, IChannel channel, Int32 idChannel)

The thing is that I *do* have a software encoder installed and it can be used to scan channels on the other analog tuner without any problem.

My first thought was that I have somehow done some damage to one of the hybrid tuners, however I am still able to timeshift on both DVB-T tuners at the same time and on both analog tuners (individually) with MediaPortal/TV Server. I *am* experiencing other problems with the same hybrid tuner in other applications. For example, in Dscaler I can get audio but no video from the analog tuner (other analog tuner works fine) and in VLC attempting to use the DVB-T tuner fails (other DVB-T tuner works fine).

Any ideas?
TIA

Ended up doing a complete uninstall (including DB and all user settings) and reinstall, and this seems to have fixed the problem in TV Server. I don't really like having to do this because it takes several hours to rescan, rename and regroup my TV and radio channels. Oh well...
